Is This Real Or Inside Of My Head?

I think I may be gifted. I've had paranormal experiences on and off since I was very young. I've seen spirits, heard spirits' voices. I've had them get physical before. At times, I only feel a presence. Other times it's a flash of an image, word, feeling, or thought. I can pick up on things about them. It's the same as if they were a real physical being. Rarely will I hear things out loud. These experiences scare me sometimes. I try to stay as closed off as I can. I also dream things. I've had dreams of deceased friends and family members. It's not a normal dream. It feels like we're actually visiting with one another. Just in a dream setting. I've predicted the sex of all my sister's children, through dreams. I knew when she was pregnant with her second child. She took a test because of me. Once I had a dream about a boy I had never seen before. In my dream, I was attacked by him. I began school shortly after that. I saw that boy in my school. He was even in one of my classes. I stayed away from him. Just in case my dream was true. I can pick up on feelings or thoughts of others. I pick up on peoples' "vibes." I can tell if they're a good or bad person. Sometimes I know things without knowing how or why. It comes to me as a thought. These experiences don't happen every day. One year I may have experiences. Then I could go years afterward without anything at all. I prefer that. I don't talk about this with people, because they make me feel like this is all inside my head.
