dissociation, likes to play with kid's a lot younger then himself, is addicted to video games(I read somewhere sa victims do this to escape reality). Is a loner, would prefer to keep to himself then go out in a group,
Hate to say this but all this could be related to not being part of his peer group.
Starting in the first grade, I used to daydream a lot in school, was not allowed in to the male peer group because I refused to fight. ( The only way I could get approve from my dad was if I did not fight). So from first to fifth grade I hung out with the girl peer group. I also became a reader of science fiction. I became quite a loner.
The fifth grade was a very bad year for me. Not only was I raped, but my mom divorced my dad, and the female peer group kicked me out. Then I was a true loner, who had no one to play with, just hung out by my self. I deliberately tried to fail the fifth grade, so I could take it over again. Went from B's and C's to straight F's. My teacher did notice, but instead of talking to me, she called my mom in and asked her, mom told her about the divorce, so they decided it must be that, and passed me anyway.
After that I got very into science fiction, would read three or four books a day, and walk around in a dreamy state,( my way of escaping)
Hope this helps.
