Dont know if this really counts, as I was the child here and I can pretty much explain how all this came to be, but alas:

• When I was around 6 years old (?, got a really bad sense of time) I used to have random obsessive impulses, such as me forcing myself to play some sort of luck-based game, and if I lost I'd have to leave my home, or me forcing myself to insult someone. However, even though I knew it was me, I kept thinking of these thoughts as coming from 'my body', and while attempting to get rid of them, I imagined me shooting, punching, and throwing away 'my body', which I literally imagined as my lungs intestines floating around. Needless to say, when I told my parents that 'my body is telling me to do stuff', they were freaked out.

• Ive always had really, really strong fever hallucnations whenever I got ill, and one day when I was around 11 I had one that I was part of a witch cult, and I was given the task of transferring their almighty invisible head to a place where it could feed on people, but i fucked up somehow and we were all doomed or sth, and I got this existential fear that I usually get in these fever hallucinations. To my parents, I probably talked absolute incomprehensible stuff, and I just remember my mum being terrified due to me saying, in my delirium, that she was a witch.
