I have that as well and I am glad to hear, that I am not the only one. I am so used to it, that it becomes normal to imagine interactions with others and talk and laugh with them.Well, I'm not sure to be honest. When I'm offline I have conversations with different forums members as if we were actually communicating. I've created personalities in my head for each of them based on how they respond on this site. It's actually quite comforting. Sometimes I say something outloud and laugh as if I was actually speaking with them. At this point I will say I'm not crazy because I realize that I'm doing that. In another decade I might not be able to distinguish if I'm really communicating with them or not. I think then I could say that I'm crazy.
But, I really don't have a problem with that because by doing that I never really get lonely. I have all these people in my mind that I'm communicating with. To be honest, I think it would be great just to be completely in my own little world laughing and talking to the NICE forum members, skipping the names at this point, detached from reality while someone cleans me up after I crap all over myself and takes care of everything for me. Reality is over rated.
FYI: Since I joke around alot I should point out that I'm not joking about what I just typed, hence no Ha! ha!
Now I'm curious about the jokes you've made (^_^)
