Hello! I am 16 years old, and i have strange things happening in my head. I sometimes see a bright light flicker in my head or at least i think it is in my head, and i flinch. Sometimes I see animals mouth move and they speak to me and i hear the words plain as day. Once or twice i saw like a jaguar come towards my face as if it was going to bite me. I have been bitten by a dog before. I also have imaginary worlds in my head, and my friend in my head is the main character. It is like I am narrating a story in my head. I even have a continuous story in my head in which i am the main character, and horrible things happen. So is it normal for me to have all these strange things in my head? Are these things effects of schizophrenia?
