A Developing Sight

Ever since I was younger, I have been pretty precognitive. I come from a family of "witches"- my great grandma and great-great grandma were always called for their abilities (getting rid o headaches, helping someone in the hospital, getting a baby to stop crying), my mom can feel energies and was slightly precognitive, my youngest sister can strongly sense energies, sees faces, has had out of body experiences and has had visions that later came true and my other sister has had clairvoyant dreams. Recently tons of things I have been saying have been coming true-little things to big events. For example, once I joked my mom's car broke down and we wouldn't be able to call anyone-it happened. Another time I joked my friend would be hit by a bus- two days later she was seconds away from being hit by a school car in the school parking lot. Another time I was thinking how much I'd really like to have a ring to wear like daily. The next day when I went shopping, I was looking for the ring I had pictured in my head. When I went to a store there was nothing there but when I went back... There was the rings exactly how I pictured them and only one left and in my size. I also had a dream that a parapsychologist I was talking to told me that I was precognitive and the next day I got an email. However I also just randomly said my fish,dahlia, was going to die one day and he did. Another time I had a dream about the death of my great grandmother on the night she died (October 31 12:00am) which way odd because I'd only seen her twice before she died. Sometimes my "abilities" are good/helpful. But the times I really wonder if its not a curse. Any suggestions on how to control it or have it help more.
