A girl I knew had a selection of very, VERY weird beliefs, some carried on until she was about 11.
Both of us watched a particular show (Dragonball Z) and the characters on it could fly and do other such super-human feats. For months (aged 9ish) she reported that her favourite character visited her at night and whisked her off on adventures. Me and my sister were truly weirded out when she recounted her night-time journeys as we knew it wasn't possible. She apparently didn't.
The same girl also believed that she could fly (a belief I'd had, then dropped aged 5) and insisted on demonstrating to us her 'powers of flight' (the highest possible jump of a ten year old). She apparently also attempted to jump from her window, but was stopped in time to prevent her 'flight'.
She also harboured the belief that she was gifted with various special powers e.g. mind reading. I'm not proud to say I played along and encouraged her.
Like almost every other weird kid, I networked with other weird kids.
