How Do I Deal With Spirits?

I have "seen the future" through dreams and "visions" and have been able to pick up on "bad vibes" ever since I can remember.

For instance, about five years ago, I had a terrible feeling in the pit of my stomach. I wasn't sure WHAT was going to happen that was so terrible, I just knew something was going to happen. I begged both of my parents to stay home. When they forced me to go to school, I threw a tantrum because I just didn't feel like it was safe to leave the house. Once the school day was over and I came off the bus, my house wasn't there. I was informed that it burned down later that morning.

Later that year, it was my mother's birthday. She decided she wanted to go roller skating for the day. As soon as she said that, I immediately got a bad vibe. I warned her that we shouldn't go, that something was going to happen, that it would be safer just to go bowling, but of course, no one listened. We, as a family, did what she wanted to do for the day. When at the roller rink, my mother tripped and fell. She broke her ankle and needed two surgeries for it.

An image of my mom getting into a car accident popped into my mind. Afraid for my mom's well being, I warned her ahead of time to be extremely careful on the roads, a week later, she was in an accident. No one was harmed, thank goodness.

But now, I keep seeing images of people everywhere. I look and sometimes I even know their names, without any possible way of logically knowing. I've always been fascinated with the paranormal, and I think it's hereditary from my mother's side because my younger sister has the same occurrences as me and my cousins from my mother's side have told me about their "wacky dreams" or "wild imagination".

Now though, things are beginning to get more complicated.

Recently, I've been having significant dreams. One with this specific girl (late teens, blonde) and warnings from her. Saying to "stop her. Get her." and to "help." I've never seen this person before, and these dreams terrify me. Spirits before have come to me before looking for help, and I'm not sure how to help them without scaring myself or putting my, and/or anyone else's, well-being in danger, so I ignore them, which I know is worse. I know this isn't normal, so can someone please help me and/or give me advice?
