What obscure things give you a little scare every time they happen?

I guess this is kind of obscure, I'm someone who deals with severe and dangerous parasomnia, where I'm a danger to other people and others, parasomnia is a sleep disorder that causes you to sleepwalk and have night terrors and such. My condition is interesting because I have non REM sleepwalking, which it allows me to actually coherently respond to people and use fine motor skills to unlock doors which I'll regularly make harder to unlock because there have been many occasions where I just walk out of the house, It still doesn't matter anyway because I carry enough intelligence while sleepwalking to remove those things, and I don't even have any recollection of it happening, it's very scary to think that I can interact with people and be a danger to them and myself, while my brain is allowing my body to move without parts of the brain being active to allow a consciousness. Night terrors are no better, and in fact are more dangerous, I'll wake up with an altered state of mind, usually induced by extreme fear, I once and Drew blood from my own father by punching him because I woke up from a night terror, and started beelining it out of the house onto the street. Yeah, not fun stuff to deal with and I can only imagine how scary it is for my family to have to deal with it
