Is it normal that i have "people" in my head?

As long you understand they are not real and you are the creator and don't cause any trouble for your self and others then do whatever makes you happy infact, if the above are the case you don't have to go to the doctor.

Don't listen to these jackasses who are telling you you're schizophrenic. You clearly specified that they're just characters you made up and they don't try to control your life.
I do the same thing. I have a friend named Lilly, who I often think of as my conscience. Other times she's just a friend. And she hasn't told me to kill anyone so far. ;)

Well, you're only crazy if you didn't intend for them to be there. But if you're just making up characters like a writer would, and imagining the types of things that they would say...then your not necessarily crazy, maybe your just incredibly bored.

everyone talks to themselves and sometimes in different 'personalities'/ways, you just seem to have taken it a step farther to give them names. It's perfectly normal, but i'd say not normal to think that these people 'are not your own thoughts,' and think of them as separate entities.

Well, no but I do too. I hope you're telling the truth cuz I'm abouts to tell you about the people in my head.

One is a little girl, I call her Alice. She's sweet and she always wants to play with me.

Another is a lady. She's always crying, always so sad. She whistled me to sleep once.

Lastly there is a man. He is around my age and is always either angry or acting immature.

It's not really normal, no. Could be MPD (multiple personality disorder). I sort of have the same situation, but my "voices" are my own, just... they have their own personalities. One is very cruel, jokes about things I fear (i.e.. "there's a spider right beside you!" when there's not), and is just negative in general and is abusive. The other one is very nice, supportive and helpful.

They're my own voices, and they're not real people. I know that. Just like you know (or at least you should) that the two in your head are your own creations, even if you did it subconsciously and don't recall doing so.

I have imaginary friends too, one of them is a flying bunny, another is a kitty cat...

It must be nice because you are never lonely.

It may be fun, but my brain is just to powerful and controlling to allow thoughts that are not my own.

Stop telling me how to live my life.

I have an inner monologue that is so strong it prevents external ones from taking place correctly.

When I'm talking to someone I hear them and reply, but it's not attached to my inner monologue.

So all my conversations are one sided, with the other persons opinion meaning nothing to me.

People seem like one dimensional cartoons. This is how people in the narcissistic/antisocial/psychopathic/dissocial spectrum mostly think, and how they see others.

I have this to quite a severe extent, it even shows in my postings.

Does it apply to you?

I don't want to be unkind, but let's call a spade a spade: you have schizophrenia. Please talk to a GP real soon and he will refer you to someone who can help. The medication these days for schizophrenia is much better with less side effects and many people with mild schizophrenia can live productive lives.
That said, if the voices aren't bothering you, I don't see the problem. However, often they start out benign but eventually become bothersome, stressful and much worse. Better to see a doctor now than to wait and see what happens. Don't worry - you're not alone. SO many people have mental illness.

Why do you even bother posting this crap?

Ofcourse it's not fucking normal

Seek help you freak of nature

^agree! See a doctor, it doesn't seem bad right now but it can eventually turn bad; &this is one of the symptoms
good luck!
