Seriously, I don't think there's anything paranormal in any of that. I probably believe in angels and demons and prophecy and all, but it's not something I give much thought to usually. But these sorts of things are more or less aberrations in the mind. Memory is a tricky thing, and can be quickly overwritten. You say you've dreamt things like such and such before, and then it happened? You mind could have forged the memory. It does happen. Look at a clock sometime, with a ticking second hand. If you catch the right moment, the second hand will seem to hold still for two seconds. Obviously, that's not the case. But you actually SEE it. Right there with your own eyes, it holding stilll. Someone else who's been watching the whole time will tell you otherwise. See, as your eyes shift on the image, it can only half-see things for the first bit. It can't be sure where the hand was for the first second, so assumes (wrongly) that it was where it is when you first look at it. Thus, an entire second of false memory is forged by your mind. I suppose it's a sort of hallucination, but you can test it whenever you want, and is really easy to see.
Anyway, that said, your brain can do tricky things, and really deceive you.
Oh, about the dreams manifesting physically... pain signals are just nervous impulses. Your brain can manufacture them. If you're hurt in your dream, I'm certain you can wake up and actually feel ghost-pains for no reason other than that your brain is telling you to hurt because of something you imagined. The cut for justin is the other way around, likely. You probably accidentially cut yourself while sleeping (or your body noticed it while you were sleeping) and manufactured the dream as it was considering the injury. Thus the dream didn't cause the cut, but the cut cause the dream.
Okay, here's a funny little memory thing with myself. Most of you probably know Star Wars, and how George Lucas added in Midichlorians in '99 with The Phantom Menace. Well, I have the distinct memory of, when first seeing it, that... okay, backtrack for a second. I used to and still write. Way, way back I used to write fanfiction type things, particularly Star Wars. Now, back then I was a bit more anti-secular, and didn't quite like the whole religious aspect of Star Wars. This was definitely back before TPM came out. Anyway, I was thinking about writing fanfiction, and I often thought about say, the origin of the Jedi knights. Problem was, I couldn't reconcile the mystical Force, so I tried to give it a rational explanation (keep in mind, this is what my memory tells me.) Now, I distinctly remember thinking one day - I even remember where: during camping in the mountains, next to the car - that I could make it a sort of bio-engineering thing implanted that gives the Jedi the abilities. Now, later I did write a few very short segments to this effect, but THOSE were after TPM. But somehow, I think the original thought for it came well before the movie ever came out. Now, really, did I happen to think of that self-same thing? I suppose it is possible, considering that I didn't feel comfortable with writing about the Force at that time. But likely, I could have a rogue memory - I could have impressed my later post-TPM knowledge of the Midichlorians back on a memory in which I was considering possible origins for the Jedi knights.
What I'm trying to say is, the mind and memory are tricky, and I wouldn't be too certain in trusting it.
