For me, when I was young, I always used to cover my neck when I was sleeping after I had a recurring nightmare about a spear coming from the ceiling and stabbing me in the neck. I think I started getting those nightmares after watching a movie with some brutal fighting scenes lol. Also I used to be super scared of stairs like this
especially when they went up to higher levels, because I was scared that I'd fall between the holes.
I'm over those stuff but now before I sleep, I always close the closet door (which is to the right of my bed) and close the curtains for my bedroom window (directly in front of my bed) so that there is absolutely no gap because the view from my window is prettty creepy at night and I've watched too many horror movies lol. I also can't sleep without any light, like I start like panicking or something if there's no light. So my night light is pretty bright.
What about you guys? What are some irrational fears you have?
