I Need To Know What's Going On

So quick back story. My father's grandmother was a bruja (witch in Spanish) in Puerto Rico and she did a lot. Everything from exorcisms, spells, and using a crystal ball. My dad has seen her do these things but she never taught him or his mom anything. My dad still has experiences like seeing demons, ghosts, and having premonitions but he can't do the things she could because he doesn't know how.

Ever since I was a kid I have had a huge predilection towards things like this and I never knew why. It felt so natural to read about ghosts, to hold a crystal ball, and I always thought that everyone could see the man in the corner. The thing was, there was no man in the corner, not to anyone else. But I could see him. He followed me everywhere, tall and in a suit and top hat doing nothing but watching me.

As I got older I started seeing people crossing streets and disappearing when a car got near, people in my house that no one else could see. I would have dreams warning me not to go certain places or strange coincidences that would happen to prevent me from going there if I didn't listen to my dreams. I would have accidents like dislocating my ankle before my trip on the Queen Mary (which happens to not have any ramps for wheelchairs) and the day after the trip I couldn't go to I would have a dream that something (a blue orb, a voice, a person) that would fix whatever was wrong with me that prevented me from going.

I usually get feelings in areas also, like sadness, fear, or paranoia where people have experienced things also. And I have noticed that the classic "make a birthday wish" that usually never works for kids always seemed to work for me. My parents always tell me that. The universe listens to you and if you will something to happen then it will. It's always seemed to be the case.

And my mom, when she was a kid, used to have premonitions also but because the family teased her she forced herself to stop and slowly the visions stopped and now she can't do it at all. My grandmother (on my mom's side) is very religious but I really want to find out what is going on. Is it possible that her powers or whatever got passed on to me and my dad? Could I do what she did all those years ago? I would love to if I could but I just don't know how.

If anyone could tell me what's going on, or any information on how I could get any information or education on witchcraft that would be amazing thank you.
