Is it okay to have full blown conversations with yourself?

I didn't know where else to ask this question. I apologiseif this is is not a correct area. But for the longest time I've been talking to myself. I don't just say simple things such as "Need to call my father" or solving questions and the likes aloud. I just have full on out loud conversations with myself. They'll go on until I know someone will overhear me talking to myself - it's like I can't stop! I'll try to stop but I always start back up again. Theyre complex things too, I'll talk to someone who isn't there about what I'm doing, how my friends are doing, explaining my actions, make up stories about what I did, etc, etc. It's not like I don't have anyone to talk to - Im a pretty popular person and I'm no introvert, but I can't stop! Though that's not even the worst part, when I talk to myself I take on a new identity. I'll take on a new name, appearance, lifestyle, etc. I know I'm not actually this person, but I'm starting to get really concerned about myself...

Sounds kinda fun! Sure, why not!

I talk to myself a lot too, especially when nobody can hear me. It's pretty much thinking out loud and getting a "second opinion" I'm not worried about it, I think a lot of people do it.

Something I do a lot too - I sometimes also catch myself and then it starts to feel 'odd' talking to myself, lol.

I think it's actually fairly normal, and most people would do it sometimes.

Oh, I think that's pretty normal. I actually am 3-4 persons. And often I think out loud or argue with myself. In my opinion that's normal. Not every person speaks their arguments with themselves out loud but almost everybody does it, I guess.
