I was talking to my mother today. And a thought just popped into my head. It's weird saying it outloud, but it's normal. But then I heard a voice (to describe it, not a "physical" voice, but like some one just slide into my head and whisper thoughts into me). It just jumped in mid-thought; "You're a presumptuous moron." It wasn't an abstract thought or feeling --- but it's like some one's actually TALKING to me inside my head. I told it inside my head, "Shut Up." And then I just partially shut out. It keeps intruding my head. It isn't my thought. 

I do feel intruded, but I know it isn't the same thing because I know this voice is different from the other one. Even when I talk to people who died/people who didn't exist/people who I knew from the past inside my head it's never like this before. Recently, I suddenly realized that there were two other presence inside my heads for years. They feel more abstract --- sometimes also direct --- and they're comforting &amp; guiding. They make me feel sane. When I close my eyes and think of nothing, their presence accompany me.

But this voice is different. I see things. I feel intruded. I dream &amp; feel things. Several others also saw them, too. This particular voice is like an internal... I don't know how to describe it anymore.
