Is This Real Or Am I Crazy?

When I was 7 I had a dream about my grandmother dying - the next morning when I woke up, my parents told me that my grandmother had died that night. All my life I've heard voices but always thought that it was an "active imagination" - the voices always sounded like little kids asking for help over and over again. I've also always seen shadows and "people", I don't know if I should call them people because they're obviously dead, but obviously were people. I see these dead people like they're living life and regular people, but sometimes, they talk to me and try to tell me information that I don't know what to do with. It scares me a lot of the time and I feel really bad that I can't help the children who talk to me or help the dead people who ask me to do things for them and their families.

I also always feel that they're someone watching me and I always feel something lightly tugging on my hair. I don't know what it is or why it is. Out of the corner of my eye I always see shadows and demon like, things, moving or standing there, but when I look again, nothing is there.

I've been put into a lot of therapy and even hospitalized for the voices and dead people and effects from that. I'm constantly told that I'm insane or stupid for having these things happen to me. I really don't know who or what to believe anymore. I do enjoy the dead people because they're nice to me and I can talk to them about anything.

I don't know if this could be trauma from previous events at the very beginning of my life and it's become more intense with more and more situations over the years, or if I really am able to communicate with and see people who have passed on and such.

I'm just looking for ideas and answers from other people. I'm 14 now and everyone hates me because of all this "out of the norm" stuff happening to me.

Please help me!
