In need of some dream analysis

I'm not sure what's going on, but I've been having the funkiest dreams lately. Actually, they are more like nightmares. In the one I had last night I was hiding from this group of mob-like men. When they all got in their limo, I took out this huge beautiful silver gun I'd been hiding, stood up, and unloaded on the limo. I could totally see all the blood splattering and each one of the guys die. It was actually a pretty gruesome dream. Then two nights last week I had dreams about being in a car crash. Both crashes were pretty intense and I think I was dying in one of them and woke myself up. I don't know what all these bad dreams mean, but they definitely make for a restless night of sleep. I feel super tired in the mornings now and have even reverted back to drinking coffee. I have had a couple fun dreams I can remember. My friend Jason was in both. I can't remember the first one but the second one I was playing poker at his house (which I know was brought on by Shawn and the guys' recent poker night). The crazy part is I got totally drunk while playing and passed out on Jason's couch because he wouldn't let me drive home. What a good friend. Actually, when I woke up the next day, I felt more well rested than I have in a few weeks. I guess dreaming about sleep is a good thing.
