I'm Seeing Ghost

All my life I have been different I have never really fit in. I have had some really weird experiences. I'm 13 and I can read people's minds very easily, dream the future, I can control all the elements, I can also talk to ghost, and speak this weird language I have never heard. Me and my older brother are very powerful psychics we have always been able to do most of any ability you can name without hardship. Since we were small we have been able to talk to ghost but we moved our mom bought a house in the middle of know where. Him and I decided to take a look around and venture out into the woods, well we found this old house that looked like it was from the 1800's and it was also abandoned so we decided to look in it, well right time we stepped on the porch we heard a loud scream, our reaction was to run back home but something stopped us we saw three figures and they were definitely ghost and they gazed and suddenly disappeared. So we went home scared out of our minds to only find through the next couple of months they had followed us to our new home. Over this time my brother thought he was crazy and just left the subject along but they still bother him. But I never left it alone I couldn't, they would call out my name, I could feel them staring at me as I slept. Because of this I decided to try to reach out to them to see what happened, I did and it turned out there was a little girl named Rachel her mother and her father who was a tobacco farmer. But now it is starting to get crazy, the mother is giving me nightmares about how to kill me but she does it through the elements such as if it's raining when I go to bed she will kill me with water, if it really windy she will kill me with air. The father is replaying how he died over and over, he shows himself coughing (he was very sick) and rocking himself to his death but before he dies he will look me right in the eyes and then disappear. But the worst is they girl Rachel she sings me to sleep and tries to drive me crazy and lately I have found myself speaking that weird language and having weird conversations with myself and I have no idea what I'm even talking about. I think she is inside of me. But is that even possible? So please comment and give me some advice.
