I don’t know if this is funny, but I believed my brother in law surgically planted cameras in my cat’s head to record me. So every time my cat stared at me, I froze in fear of being recorded on the toilet or in the shower.
When I was 7 I was in elementary school and i really had to use the bathroom.
So some older kids tried to scare me saying that the bathroom had a ghost in it that would steal your soul oooh spooky
and I was terrified because i 100% believed them but I used the bathroom anyways.
I ended up thinking that I was the ghost/possessed by the ghost and I then proceeded to try and steal all the big kids souls to the point I thought I had to bite them and suck their souls out kinda like a vampire.
Lol everyone was so weirded out. And after a stern talk from my parents I thought I couldn’t be possessed anymore cause my parents must have scared the ghost away. Cause they scared me even more than the ghost did lol.
When I was really out of it at the hospital, I asked a staff member if anything would happen if I ate an apple since I associated it with the forbidden fruit from the creation story (my delusion was heavily religion-influenced).
When I was a kid, I believed I had escaped from a government prison for child assassins, and they were looking for me by scanning for a scar on the back of my hand. Every passing car and toll booth was capable of scanning, and the only way to hide from them was to place a pink Starburst wrapper over my hand to confuse their sensors. So I would walk around school with Starburst wrappers taped to the back of my hand, and everyone was baffled by me.
This isn’t a delusion, but when I was a teenager they tried putting me on antidepressants. They made me super manic and I landed right back in the hospital again. They had no beds, so they put me in the padded room. Well, don’t ask me how I did it, but Manic Ninjastar managed to climb the padding all the way to the ceiling. When the nurse came in to check on me, I jumped down and shouted, “BATMAN!!!”
I do stuff like that to people all the time just walking down the hall not even meaning to. I’ll walk behind some old lady, not knowing I’m there, it’s all silent, I’ll say “HEY! How’s it going?” And they jump and scream every time lol
