I live another life inside my head, is this normal?
So I have this other life inside my head. I'm mostly in it while I'm trying to go to sleep, although I go to it during the day as well. However it's not me living my life, it's another person that I've created. I make up scenarios and live through them in her. She even has a backstory and everything. I won't go into detail about that because it's irrelevant...the thing is, though, I can sometimes live through her/my point of view and other times It's like I'm playing some kind of Sims game where I'm the controller and she's the avatar but I can exert my emotions and thoughts onto her. Also, some of her characteristics don't match up with mine. For example, I'm shy and quiet in my normal life, but in her life I'm outgoing and friendly with the other people in her/my world. Lastly, I also feel that she is taking over my life. I don't date guys in my normal life because in her/my life, she's dating another one of my people and I feel like I would be betraying him if I dated someone. I've also began to think like her, like for example if I see something sad that reminds me of a sad part of her backstory I get emotional. Then, I find myself hating my normal life and anticipating bed time because I know then that I can go to my other world.
So is this normal or do I sound bat shit insane? Because now that I've written this down, I think I sound a bit psycho.
Also, sorry if this makes very little sense. It's a bit hard to explain but it make more sense in my head. Thanks!
