not sure if this counts as a fight question, but in stories (esp tv/movies with high visual impact) that have a character that does psychic power things with their mind or are victims of psychic powers, often they’re shown bleeding from their nose or ears to illustrate when they’ve “overdone it” (re Stranger Things) or if they’re overcoming psychic control (re Get Out) and i’m curious why that is? is it just pressure on the brain and blood coming from the nearest orifice? what are the logistics?
It’s a burst blood vessel. Or, sometimes, multiple ones. This is a real condition that can happen. Not the psychic powers, but if you’ve ever coughed, sneezed, or vomited hard enough to get a nose bleed, same thing. This can also lead to minor hemorrhaging in the eye. Unless it’s happening frequently, this stuff isn’t a serious medical issue, just an annoyance.
Bleeding from the tear ducts or ears is less common, but It can happen. If it’s a one off thing, a ruptured blood vessel in the nose isn’t usually something you’d need to worry about, unless it’s recurring. If it does happen repeatedly, than you should probably see a doctor.
