Was i a witch in a past life?? or am i just a lil weird?

Hi everyone! I was just reading some of the posts and alot of questions came to mind. I seem to be able to know when someone is looking at me when i'm turned around. I get this feeling that just overcomes my body. I also seem to think sometimes that i'm not alone...(even when i am alone) I've been able to sense this since i can remember. I sometimes feel like maybe i can comunicate with the dead. Never have tried, but for some reason i think i can. Just this feeling that doesn't go away. And i always feel like there is a presence around me at all times. Can someone explain this to me pls?? I'm also very interested in witchcraft and all of that but growing up i was always tought to never believe in such a thing. My parents said if ur a witch ur worshiping the devil. Which i don't believe that but maybe someone could explain the beliefs and so on.......hope u guys don't think i'm crazy! lol
