Am I A Psychic, Medium, Clarvoyant?

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 the toilets which was located in the basement of the center, when something very weird happened. Then there was a rush of cold air and a white shadow that rushed right past me. I thought this was really weird, and I don't know how science would explain what happened. Neither do I think that any of these experiences are coincidental.

Sometimes I can feel what a certain spirit looks like and the energy in a room. I am also very good at reading emotions of others. I really want some help from someone that is perhaps a medium or any other experience with these things.

Thank you:)
