Today I had a heated argument with my mom that she thinks that im mentally ill and should seek psychiatric help because she overheard me talking to myself. Well I do, I reason, create arguments, tell jokes , all to either myself (me in my head, the subconscious, ego whatever you wanna call it) in the past or theoretical future interactions with my friends, relatives and colleagues. I don't see or hear anything and anyone, don't feel any presence or anything, just talking. I'm 21 and I've been doing it as long as I remember. The conversations aren't psychotic or paranoid, they're mundane, maybe entertaining to me but not ecstatic.
Is it normal or not really?
