Is It Empathy?

Ever since I was little I've always had these feelings or always knowing something. When I was four I was riding in the car with my grandfather (who is now passed on) and out of nowhere I said "don't pass that car." There was a three car pile up ahead. I've always thought that maybe I had some sort of power, but growing up in a christian only family, made me feel like an outsider and that there was no such thing a "powers".

Lately I've been sensing the feelings of others around me. I went through a lot of deaths in my family. My great grandfather committed suicide, my great grandmother died not long ago, my grandmother died, and my grandfather died. My mom doesn't believe me. But I think this is genetic, my mom had a premonition or however you spell it about her grandmother dying and then like two days later she did. I think that since I've been through a lot of deaths I have a closer connection with the nonliving. I get the feeling that my great grandfather has not yet passed, but still lingers around in my grandparents house. But I don't think of paying any attention about that. When I go over there, like in the bathroom were he committed suicide, I feel as though I can feel his pain. Maybe this is all in my head. My aunt has empathy, I think.

Can anyone tell me if this is crazy or do maybe I have some sort of power?

thanks.
