Irritating Dreams Or Coincidence?

I've had some very coincidental dreams, in my opinion, they were just absolutely pointless to have.

There are three times that I've dreamed something like this and every time it's about a person who is... Not so important in my life.

The first time this happened, I was in high school. I dreamed a horrible dream in which there was a fight going on. A person was being "jumped" by numerous people, there was a crowd surrounding them, and in the dream I could not help at all. I was crying and pleading for other people to help this person but nobody paid any attention to me, just ignored me as if I didn't exist. All I could do is watch this poor person take on a beating.

The next day my friend and I get a phone call from our friend Joe who says he needs a place to stay because last night (the night of my dream) he was jumped by a group of guys and beaten with a skateboard (he was homeless at the time and had slept in a park). I told my friend about my dream and both of us thought it kind of strange. I think it's even more strange because Joe and I were not that close at all.

I don't know how long after that dream it was before I had another one like it (maybe 6 months), there was a person involved in a vicious beating whom I could not help, again.

The next morning our friend Dean calls and tells us he's been jumped by 3 guys and got it pretty bad.

Again, I am not, nor have I ever been, close to Dean. I felt bad after hearing this sure, but that's about the extent of my pity. Honestly, I was more involved with thinking about my weird dream and how it connected to him.

So, third dream I had was about 7 months ago (it's been a few years since the last 2) and it wasn't a DREAM per-say, but I woke up in the middle of the night (1am or so) with a feeling of absolute terror. I've never experienced such a feeling that would wake me out of a dead sleep. I wasn't having a dream, just the feeling.

I was so scared I didn't move for a few minutes. I heard a very faint yell from outside while lying in my bed. I thought it was weird, so I prayed and I went back to sleep. The next day, my fiance tells me this guy, Matt

(he used to room with us and works with my fiance & stepdad, he has a lot of issues with drinking etc. So my mom kicked him out)

was jumped by a couple guys he was trying to sell heroin to at the church (which is almost directly behind our house) the night before, about 1 am.

I think the terror I felt upon waking must have been connected to Matt and the faint yell I heard was ACTUALLY him, at the church.

But why, why, WHY would I have dreams like this connected to people I'm not necessarily that fond of or close to? How annoying! It's not as though I'm able to stop it from happening in real life anyway so why bother having them?!
