Mmm intresting...
Yes indeed i do think that the voice you can hear is your conscuence but what about talking to yourself with it? As in asking questions for example...
Or just preparing something to say or think something over in detail...

As far as problems are concerend in the area i've heard that for instance walking around without a goal like walking in your room in cricles is a sign of a problem... I don't agree with that but that's one of the things i've been told by nomerous people...

How about acting on your own voice? Like laughing or something like that.

Personally i handle a lot in my head and think it over by walking. At more then one time my mum actuelly asked me why i was laughing (something i was thinking off) or if i'm really upset about something and i'm running it trough my head i can actuelly start making jestures to go by what i'm thinking... Personally i don't think it's odd at all... But since somebody on a board started a thread about this all and we started discussing it peopl's reaction to it and different opinions i found pritty intresting.

That actuely is a very nice statement funnygirl
