WHen I am alone is when I am paranoid. Ill hear whispers that aren't there. But not words? Its like just something carried on the wind I guess is the only way to describe it. Like there are thousands upon thousands of creatures lurking just out of sight. Talking just loud enough that You know they are talking. But you can't understand what they are saying.

They told us not to believe everything you see on TV, but I heard somewhere that the movie "A Beautiful Mind" is one of the best representations of schitzophrenia out there. And he had the same(or near the same, hard to remember, i could be completely off)symptoms as what you described.

And once again I say this to everyone, THIS IS NOT A RECENT THING. IT HAS HAPPENED ALL MY LIFE. I agree teenage horomones and growth could enhance it, but IT IS NOT A NEW THING.
