One of your smartassed friends probably hid a tape recorder in your room. Confront your smartassed friends.

I'm confused. Why would my smartassed friends put a recorder in my bus and bathroom? And classrooms?

How can you find out if it's normal if you don't explain your problem properly. I think I know what your talking about though & my advice to you is go see your GP about it, don't know worry they won't commit you to an institution. I went to my GP with this and other symptoms and it turned out I had a low level form of OCD

I think this is normal. I mean, you can't have complete silence inside of your head. Even as I am typing this I hear myself (although it isn't really me, but it is, just like what you said, its complicated) saying what I'm about to type; now that I'm aware of what I'm doing its like really kinda weird actually. But anyhow, yeah I think it is comletely normal. Another person responded about it perhaps being some mild OCD (obsessive-compulsive disorder) and I would agree that when it gets to the stage that you are at where it is starting to drive you crazy it is likely OCD. It's kinda like having a particular song stuck in your head and you can't get rid of the song... but that actually might be a solution... try listening to music and your inner-voice will likely go away! Your doctor may be able to prescribe a medication that may help decrease the OCD-aspects. Best of luck to you!

what's with the medication ? It's perfectly normal to talk to yourself. To cheer yourself up, to analyze a situation, or whatever... Unless these voices are telling you to do something you'd rather not do, this is NOT something to worry about.
Just my 2 cents...

Dont worry your perfectly normal . . . for a schitaphrenic.

When you think of something to say, how do you know you've thought of it? How do you know what it is? Do you have any idea what is going to come out of your mouth before you open it? If so, how?

In my experience words form in my mind, and the conciousness of those words sounds like my own voice. The more I concentrate on them, the more they tend to echo and repeat inside my mind. When you think through a chain of reasoning or read silently, you have to have a stream of words in your mind somehow. Everyone must.

When I lie quiet before sleeping I sometimes notice that there are other words, more elusive on levels below the clearest words. Thoughts emerge from other thoughts, barely heard statements that you choose between.

Now what I think isn't normal. Or isnt' OK anyway, are those people who think that thoughts inside their own head are God talking to them or something like that. No matter whether the voice seems to be saying "Give all your money to the poor" or "Kill your parents" its still a misunderstanding of a natural phenomena of conciousness, the auditory interpretation of pre-vocalized notions.

Hey, I know. Next time you hear it in a public place ask a stranger if they heard it, too. If they look at you funny, just tell them you have an ear infection and you can't hear well. If it's a chronic thing, go get checked out - I think that's indicative of schizophrenia.

Hey. I think as long as you know the voices aren't real, as long as you don't feel compelled to do what they tell you), and as long as they don't interfere with your life, you're fine. Lots of people hear voices--it's even normal to experience hallucinations once in a while, particularly when you're falling asleep or when you first wake up. I've read that the difference between normal hallucinations and mental illness is the ability to separate what's real from what isn't. Of course, you may want to talk to a counsellor, just for some professional reassurance. But I'm pretty sure you're not insane.
