So here's the thing. A few weeks ago, we was looking for a house to rent so one day we found one that looked nice. But as soon as I walked into one of the bedrooms upstairs, a wave of negative energy hit me. It was really weird because it didn't stop there. I got a feeling and a picture in my head of a person that had died in there. I saw a man with a blue plaid shirt and brown overalls with a straw hat. When I went out of that room the energy was back to normal. My grandmother also is sensitive to energies but I think my ability goes beyond sensitivity. I do not think that I can communicate with them, not that I have tried, but it seems to real for it to be in my head. I have also had other incidents with spirits. In my school, which is quite old, I was in the toilet washing my hands when I felt a rush of cold air in front of me and cramps in my stomach. Another time at a shopping center, I was waiting for my mom outside a toilet, which was in the basement of the center, when there was a rush of cold white air in my face. That was my first ever experience. In the house when I saw the man, I couldn't see a man standing there. But I could see it in my head. It is hard to explain. I have one other thing I am confused about. Deja vu. I have researched about it, but all the websites say that there is a scientific explanation. But I don't just have deja vu, I am getting Deja Vu of having Deja Vu. It is starting to get really creepy, and I am starting to wonder if I have dreams without knowing about it of the future!? It sounds really weird, but I am very curios about what is happening. Please help!
