Spending nearly 5 hours on an assignment worth only 2% of a mark normally doesn’t feel great but my grad student mentors said that my rough draft exceeded their expectations and they had no big comments on the final draft and that’s worth soooo much more to my ego than 5 hours teehee.

thinking about foundations... sick to my fucking stomach. yeah i'm gonna fix my heart and maybe build an alter where it swells. what the fuck

[styrofauxm]

me before wwwy: it sure would be cool if mcr dropped an album soon

me not 10 minutes after wwwy: i need mcr to drop an album right now and stop playing with my heart

[samarashoot]

truly hate to weigh in on discourse but i would love for everyone to practice recognizing when you're making up a guy to get mad at. your life will be so much better. yes this is about every variant of those "mcr fans listen to other artists challenge 🙄" posts and my take is

who cares

every response to these posts that just recommend other bands in the nj hardcore scene or direct cited influences on mcr are also fundamentally flawed because they miss what sets mcr apart from those bands which is their very specific brand of dark campy melodrama that exists across genres

the real reason i'm making this post is to instead share my playlist of recommendations for mcr fans centered around said dark campy melodrama & which is measurably objectively better than any other because more than half of the songs are songs that i or my friends have done drag to which i have decided is the true indicator of mcr adjacency

The Anatomy of Passing Out: When, Why, and How to Write It

Passing out, or syncope, is a loss of consciousness that can play a pivotal role in storytelling, adding drama, suspense, or emotional weight to a scene. Whether it’s due to injury, fear, or exhaustion, the act of fainting can instantly shift the stakes in your story.

But how do you write it convincingly? How do you ensure it’s not overly dramatic or medically inaccurate? In this guide, I’ll walk you through the causes, stages, and aftermath of passing out. By the end, you’ll be able to craft a vivid, realistic fainting scene that enhances your narrative without feeling clichéd or contrived.

2. Common Causes of Passing Out

Characters faint for a variety of reasons, and understanding the common causes can help you decide when and why your character might lose consciousness. Below are the major categories that can lead to fainting, each with their own narrative implications.

Physical Causes

Blood Loss: A sudden drop in blood volume from a wound can cause fainting as the body struggles to maintain circulation and oxygen delivery to the brain.

Dehydration: When the body doesn’t have enough fluids, blood pressure can plummet, leading to dizziness and fainting.

Low Blood Pressure (Hypotension): Characters with chronic low blood pressure may faint after standing up too quickly, due to insufficient blood reaching the brain.

Intense Pain: The body can shut down in response to severe pain, leading to fainting as a protective mechanism.

Heatstroke: Extreme heat can cause the body to overheat, resulting in dehydration and loss of consciousness.

Psychological Causes

Emotional Trauma or Shock: Intense fear, grief, or surprise can trigger a fainting episode, as the brain becomes overwhelmed.

Panic Attacks: The hyperventilation and increased heart rate associated with anxiety attacks can deprive the brain of oxygen, causing a character to faint.

Fear-Induced Fainting (Vasovagal Syncope): This occurs when a character is so afraid that their body’s fight-or-flight response leads to fainting.

Environmental Causes

Lack of Oxygen: Situations like suffocation, high altitudes, or enclosed spaces with poor ventilation can deprive the brain of oxygen and cause fainting.

Poisoning or Toxins: Certain chemicals or gasses (e.g., carbon monoxide) can interfere with the body’s ability to transport oxygen, leading to unconsciousness.

3. The Stages of Passing Out

To write a realistic fainting scene, it’s important to understand the stages of syncope. Fainting is usually a process, and characters will likely experience several key warning signs before they fully lose consciousness.

Pre-Syncope (The Warning Signs)

Before losing consciousness, a character will typically go through a pre-syncope phase. This period can last anywhere from a few seconds to a couple of minutes, and it’s full of physical indicators that something is wrong.

Light-Headedness and Dizziness: A feeling that the world is spinning, which can be exacerbated by movement.

Blurred or Tunnel Vision: The character may notice their vision narrowing or going dark at the edges.

Ringing in the Ears: Often accompanied by a feeling of pressure or muffled hearing.

Weakness in Limbs: The character may feel unsteady, like their legs can’t support them.

Sweating and Nausea: A sudden onset of cold sweats, clamminess, and nausea is common.

Rapid Heartbeat (Tachycardia): The heart races as it tries to maintain blood flow to the brain.

Syncope (The Loss of Consciousness)

When the character faints, the actual loss of consciousness happens quickly, often within seconds of the pre-syncope signs.

The Body Going Limp: The character will crumple to the ground, usually without the ability to break their fall.

Breathing: Breathing continues, but it may be shallow and rapid.

Pulse: While fainting, the heart rate can either slow down dramatically or remain rapid, depending on the cause.

Duration: Most fainting episodes last from a few seconds to a minute or two. Prolonged unconsciousness may indicate a more serious issue.

Post-Syncope (The Recovery)

After a character regains consciousness, they’ll typically feel groggy and disoriented. This phase can last several minutes.

Disorientation: The character may not immediately remember where they are or what happened.

Lingering Dizziness: Standing up too quickly after fainting can trigger another fainting spell.

Nausea and Headache: After waking up, the character might feel sick or develop a headache.

Weakness: Even after regaining consciousness, the body might feel weak or shaky for several hours.

4. The Physical Effects of Fainting

Fainting isn’t just about losing consciousness—there are physical consequences too. Depending on the circumstances, your character may suffer additional injuries from falling, especially if they hit something on the way down.

Impact on the Body

Falling Injuries: When someone faints, they usually drop straight to the ground, often hitting their head or body in the process. Characters may suffer cuts, bruises, or even broken bones.

Head Injuries: Falling and hitting their head on the floor or a nearby object can lead to concussions or more severe trauma.

Scrapes and Bruises: If your character faints on a rough surface or near furniture, they may sustain scrapes, bruises, or other minor injuries.

Physical Vulnerability

Uncontrolled Fall: The character’s body crumples or falls in a heap. Without the ability to brace themselves, they are at risk for further injuries.

Exposed While Unconscious: While fainted, the character is vulnerable to their surroundings. This could lead to danger in the form of attackers, environmental hazards, or secondary injuries from their immediate environment.

Signs to Look For While Unconscious

Shallow Breathing: The character's breathing will typically become shallow or irregular while they’re unconscious.

Pale or Flushed Skin: Depending on the cause of fainting, a character’s skin may become very pale or flushed.

Twitching or Muscle Spasms: In some cases, fainting can be accompanied by brief muscle spasms or jerking movements.

5. Writing Different Types of Fainting

There are different types of fainting, and each can serve a distinct narrative purpose. The way a character faints can help enhance the scene's tension or emotion.

Sudden Collapse

In this case, the character blacks out without any warning. This type of fainting is often caused by sudden physical trauma or exhaustion.

No Warning: The character simply drops, startling both themselves and those around them.

Used in High-Tension Scenes: For example, a character fighting in a battle may suddenly collapse from blood loss, raising the stakes instantly.

Slow and Gradual Fainting

This happens when a character feels themselves fading, usually due to emotional stress or exhaustion.

Internal Monologue: The character might have time to realize something is wrong and reflect on what’s happening before they lose consciousness.

Adds Suspense: The reader is aware that the character is fading but may not know when they’ll drop.

Dramatic Fainting

Some stories call for a more theatrical faint, especially in genres like historical fiction or period dramas.

Exaggerated Swooning: A character might faint from shock or fear, clutching their chest or forehead before collapsing.

Evokes a Specific Tone: This type of fainting works well for dramatic, soap-opera-like scenes where the fainting is part of the tension.

6. Aftermath: How Characters Feel After Waking Up

When your character wakes up from fainting, they’re not going to bounce back immediately. There are often lingering effects that last for minutes—or even hours.

Physical Recovery

Dizziness and Nausea: Characters might feel off-balance or sick to their stomach when they first come around.

Headaches: A headache is a common symptom post-fainting, especially if the character hits their head.

Body Aches: Muscle weakness or stiffness may persist, especially if the character fainted for a long period or in an awkward position.

Emotional and Mental Impact

Confusion: The character may not remember why they fainted or what happened leading up to the event.

Embarrassment: Depending on the situation, fainting can be humiliating, especially if it happened in front of others.

Fear: Characters who faint from emotional shock might be afraid of fainting again or of the situation that caused it.

7. Writing Tips: Making It Believable

Writing a fainting scene can be tricky. If not handled properly, it can come across as melodramatic or unrealistic. Here are some key tips to ensure your fainting scenes are both believable and impactful.

Understand the Cause

First and foremost, ensure that the cause of fainting makes sense in the context of your story. Characters shouldn’t pass out randomly—there should always be a logical reason for it.

Foreshadow the Fainting: If your character is losing blood, suffering from dehydration, or undergoing extreme emotional stress, give subtle clues that they might pass out. Show their discomfort building before they collapse.

Avoid Overuse: Fainting should be reserved for moments of high stakes or significant plot shifts. Using it too often diminishes its impact.

Balance Realism with Drama

While you want your fainting scene to be dramatic, don’t overdo it. Excessively long or theatrical collapses can feel unrealistic.

Keep It Short: Fainting typically happens fast. Avoid dragging the loss of consciousness out for too long, as it can slow down the pacing of your story.

Don’t Always Save the Character in Time: In some cases, let the character hit the ground. This adds realism, especially if they’re fainting due to an injury or traumatic event.

Consider the Aftermath

Make sure to give attention to what happens after the character faints. This part is often overlooked, but it’s important for maintaining realism and continuity.

Lingering Effects: Mention the character’s disorientation, dizziness, or confusion upon waking up. It’s rare for someone to bounce back immediately after fainting.

Reactions of Others: If other characters are present, how do they react? Are they alarmed? Do they rush to help, or are they unsure how to respond?

Avoid Overly Romanticized Fainting

In some genres, fainting is used as a dramatic or romantic plot device, but this can feel outdated and unrealistic. Try to focus on the genuine physical or emotional toll fainting takes on a character.

Stay Away from Clichés: Avoid having your character faint simply to be saved by a love interest. If there’s a romantic element, make sure it’s woven naturally into the plot rather than feeling forced.

8. Common Misconceptions About Fainting

Fainting is often misrepresented in fiction, with exaggerated symptoms or unrealistic recoveries. Here are some common myths about fainting, and the truth behind them.

Myth 1: Fainting Always Comes Without Warning

While some fainting episodes are sudden, most people experience warning signs (lightheadedness, blurred vision) before passing out. This gives the character a chance to notice something is wrong before losing consciousness.

Myth 2: Fainting Is Dramatic and Slow

In reality, fainting happens quickly—usually within a few seconds of the first warning signs. Characters won’t have time for long speeches or dramatic gestures before collapsing.

Myth 3: Characters Instantly Bounce Back

Many stories show characters waking up and being perfectly fine after fainting, but this is rarely the case. Fainting usually leaves people disoriented, weak, or even nauseous for several minutes afterward.

Myth 4: Fainting Is Harmless

In some cases, fainting can indicate a serious medical issue, like heart problems or severe dehydration. If your character is fainting frequently, it should be addressed in the story as a sign of something more severe.

The knowledge of some common plants

Since many people don't know most of the plants around them, this is information on some plants that are commonly seen in many places throughout the world

This is Lamium purpureum, also called Purple Deadnettle.

It's called deadnettle because it looks like a nettle but it doesn't sting you

This plant is a winter annual—it grows its leaves in the fall, lasts through the winter, and blooms and dies in the spring

Its pollen is reddish orange. If you see bees with their heads stained reddish orange, it is likely because they have visited Purple Deadnettle

This is Trifolium repens, white clover

It is a legume (belongs to the bean family) and fixes nitrogen using symbiosis with bacteria that live in little nodules on its roots, fertilizing the soil

It is a good companion plant for the other members of a lawn or garden since it is tough, adaptable, and improves soil quality. According to my professor it used to be in lawn mixes, until chemical companies wanted to sell a new herbicide that would kill broadleaved plants and spare grass, and it was slandered as a weed :(

It is native only to Europe and Central Asia, but in the lawns they are doing more good than harm most places

Honeybees love to visit clover

Four-leaf clovers are said to be lucky

This is Achillea millefolium, Common Yarrow

It has had a relationship with humans since Neanderthals were around, at least 60,000 years, since Neanderthals have been found buried with Yarrow

Its leaves have been used to stop bleeding throughout history, and its scientific name comes from how Achilles was said to have used Yarrow to stop the blood from the wounds of his soldiers. A leaf rolled into a ball has been used to stop nosebleeds

It is a native species all throughout Eurasia and North America

This is Cichorium intybus, known as Chicory

The leaves look a lot like dandelion leaves, until in mid-spring when it begins growing a woody green stem straight up into the air

Like many other weeds, it has a symbiotic relationship with humans, existing in a mix of domesticated or partially domesticated and wild populations

It is native to Eurasia, but widespread in North America on roadsides and disturbed places, where it descended from cultivated plants

Its root contains large amounts of inulin, which is used as a sweetener and fiber supplement (if you look at the ingredients on the granola bars that have extra fiber, they usually are partly made of chicory root) and has also been used as a coffee substitute

A large variety of bees like to feed upon it

This is Phytolacca americana, known as Pokeweed

It is easily identified by its huge leaves and its waxy, bright magenta stem

It can grow more than nine feet tall from a sprout in a single summer!

If you squish the berries, the juice inside is a shocking magenta that is so bright it almost burns your eyes. For this reason many Native American people used it for pink and purple dye.

It is a heavy metal hyperaccumulator, particularly good for removing cadmium from the soil

All parts of the plant are poisonous and will make you very sick if you eat them, however if the leaves are picked when very young and boiled 3 times, changing out the water each time, they can be eaten, and this is a traditional food in the rural American Southeast, but I don't want to chance it

British people have introduced it as a pretty, exotic ornamental plant. I think that is very funny considering that here it is a weed associated with places where poor people live, but maybe they're right and I need to look closer to see the beauty.

If you see magenta stains in bird poop it is because they ate pokeweed berries- birds can safely eat the berries whereas humans cannot

This is Plantago lanceolata, Ribwort Plantain

It grows in heavily disturbed soils, in fact it is considered an indicator of agricultural activity. It is successful in the poorest, heaviest and most compacted soil.

The leaves, seeds, and flower heads are said to be edible but the leaves are really stringy unless they are very young. Of course, it is important to be careful when eating wild plants, and make sure you have identified the plant correctly and the soil is not contaminated

I have also heard the strings in the leaves can be extracted and used for textile purposes

and that's some common plants you might often see throughout the world

[scientific-tricorder]

I just rewatched this episode the other day, and there are just so many other options aside from kidnapping two members of the crew and cloning them against their expressed will.

If they've managed cloning, then surely they can do IVF; they could have the crew donate gametes, which would alleviate fears about being copied and could potentially increase overall genetic diversity even more.

Swabbing cheeks would also have been just as good of a way to collect the DNA for cloning as the whole harvesting cells from the stomach as well, as well as being safer and probably more likely to be agreed to. (I think they were trying to hit on some of the adult stem cell types with that whole bit, but for the digestive tract, you'd find those as crypt cells in the intestines instead, and while success rates are higher with undifferentiated donor cells, that's in terms of a more embryonic scale and there's no advantage to using adult stem cells versus somatic cells)

Just thinking about that one episode of TNG where they come across a planet of clones where they're suffering genetic degradation from too many generations of cloning, so they request genetic material from the crew to keep their population viable and Riker just says no categorically, because of course no one would *ever* volunteer for *that*, and they just don't bother to like. Poll the crew to ask if any volunteers are willing to take a cheek swab or whatever to prevent this civilization from dying out. And it wasn't even the dumbest thing in that episode, because it was also the one where the Enterprise picked up a bunch of 19th century Irish stereotypes, together with their pigs and chickens and so forth, and also Riker slept with one of them because of course he did
