Screaming, Dreaming, And Names

My name is Rachel and I'm 14 years old. I have another story about ghosts, but there's been some new, terrifying experiences lately. First off, id like to say that I see ghosts, flashes of colors (which I have learned that what that is is flashes of spirits), and hear them frequently. I have been able to see them for years, but the flashes I only been seeing for a few weeks. And the talking is something I'm terribly scared of, and people are starting to think I'm mentally unstable.

Ive always had encounters with ghosts; seeing them, feeling when they're around, being able to tell whether they're good or bad, but for a couple months now, I have been hearing them talk to me. I hear them calling my name (and I hear the name Daphne being called too) every day, multiple times, and last night I just heard two talking at 1 in the morning, but loud enough to wake me up. A few weeks ago, I was woken up by the sounds of a car crash, an extremely loud scream in my ear, and a shove by a ghost. I have never been touched by a ghost, or had one wake me up by talking before, does that mean that they really need to contact me?

Ive also always had vivid dreams that I could remember every little detail for years. Over the last 3 or so months, its gotten worse. All my dreams are terrifying (I haven't had a happy dream in months, and I ALWAYS remember my dreams), normally with a huge amount of people being killed, and they feel so realistic I'm terrified for at least a week. They also tend to be about the end of the world and they feel so real, that after I get hurt in the dream, I wake up in true pain. I don't know what these dreams mean, but little parts of them have come true, and I didn't start having the crazy real and scary ones until ghosts started talking to me. Could that be linked? Any comments or help would be greatly appreciated!
