Am I Going Nuts? Or Am I A Psychic?

I am 13 years old and ever since I was four years old I've been having visions in my sleep. I control the future without even realizing it. But, when it happens I feel like a total buttox and I want to just crawl in a hole. For example, recently I thought before I went to sleep "what if I got invited to an extremely exclusive art show?" so then idea popped into my mind and I fell asleep. I dreamt of everything I thought of then exactly 3 months later the vision came true and my aunt brought me to see a brand new really cool type of art that barely anyone has ever seen. BOY WAS I MAD! They stole my ENTIRE idea! Also when I was around 6 or 7 years old I had the same reoccurring dream. It was I would be falling down a never-ending flight of spiral stairs. I would see distorted faces all around me just watching me fall while they whisper my name creepily. I would wake up with a start and be breathing heavy, my heart racing, and I would be sweating. I couldn't tell anyone about my dreams when I was that age because I knew I would get put into therapy or be sent to a church or something. I was really terrified. Also, my sister told me when I was smaller I scared the hell out of her because when I was asleep I sat up, opened my eyes, looked straight at her, then started to say something. I didn't know what I was saying but it was obviously bad enough because I made my sister scared of sleeping with me. In my sleep I saw the Haiti earth quake before it happened and I was mortified. I wouldn't talk for at least a week and when I heard about it I burst into tears. Also, I had a vision for weeks that I would get a very special cat with no tail that we would get off of the street and on Christmas day we went outside and found a very fat cat. We thought it was pregnant and felt bad it was in the cold. So my sister brought it inside and gave it food. My family made a connection with the cat and I refused to bring it to the pound. Now we have had my cat for over 3 years. Now, I also know something watches me and follows me. I tried to talk to it but I didn't get any response. I can feel other people's emotions too. Like the time my friend was being abused by her mother. I was talking to her and she was normal but deep down I knew there was something wrong. I asked her and she said it's nothing but once she said that I told her exactly what was wrong with her and she just looked at me stunned. My friends say they can always rely on me to protect them and keep them from harm. And that's the thing, I feel like I was put on this earth to protect everyone, whether I care about them or otherwise. I don't know why this is that I feel that I have a duty to do and I get very frustrated. My sister's girlfriend is a medium and tells me I have two guardians. But, she also tells me she doesn't know where they went and why they're not protecting me. Demons love to mess with me in my sleep because that is when I am most vulnerable. I have noticed also that I am very entranced by fire. I can make the candles flicker and get bigger and smaller. It's like when I look at them I go in a completely different world and I become only aware of the fire. Well this is my story.
