You know everyone that claimed that my Micheal Jackson did some fucked up shit. Basically later was found out to either have been lying or admitted to lying. Go ahead read his wiki.
There is also the fact that he was horribly abused most of his life. And likely had body altering practices forced on his body to maintain his voice. And you know given those things it seems pretty acceptable for someone to have major trauma. Trauma that could easily make you want to act like a child in your life or try and recapture that wonder with you know theme, parks and hanging out with other children even though it seems creepy. Because they completely lost their childhood and were abused for all of it.
