Not really stupid but I was scared of sleeping alone and mirrors at night. It's my family's fault. My mom would get me to watch horror movies with her, but the worst thing she would get me to watch is anti-drug videos, where you'd see people transition from normal looking to disgusting freaks. I was like 7-8 seeing this and it scared me to the point where I once woke up in the middle of the night and was certain I saw bald Britney Spears in my room (she had a mental breakdown and shaved her head, it was in one of the videos). Sometimes I would wait for my mom to tuck me in so I could sleep, but I felt like I was bothering her so I wouldn't ask that of her, I would simply wait for her at the stairs to go to bed herself around midnight.
Another big one was Bloody Marry. My cousin who's 3 years older than me would torment me for fun a lot, like he'd randomly punch me in the arm to the point where I had bruises, he'd allow me to play a game on his laptop but the second I got into a ranked match he'd force me to leave the game. The one that fucked me up the most was, when we watched the Bloody Marry yt video, and that night he locked me in the bathroom, turned off the lights and repeated Bloody Marry like 100 times while I cried and begged him to stop. It made me fear being in the dark with a mirror for a couple of years.
