Precognitive dream? I hope not...

Ok I don't usually have dreams like this and I'm not even sure I believe in this sort of thing BUT the only reason I bring it up is because I predicted my parents' divorce through a dream a year before it happened (no obvious signs, and I wasn't even living with them), and more recently I dreamed that my grandmother "wasn't there" as in I couldn't find her, a couple weeks before she started exhibiting signs of dementia...

So anyway this is the dream I had. I was observing some sort of "reality show" where a bunch of supposed psychics were recruited to go to an abandoned city just off the coast (no idea where) and try to tell what happened. One of them was unknowingly related to one of the people who died there. I remember standing on a dock and looking into shallow water and seeing human bones scattered everywhere. They were doing some exercise where they took a huge block of what looked like cheese and cut it up into sections and I think they were supposed to carve it into something that they perceived. I went into a sort of trance state and took a small piece and a knife and sat in someone's truck and couldn't stop myself from carving "Oct 10" into it. Just after that happened one of the "psychic" women who was there started freaking out at her boyfriend and I left with them.

I think I woke up between these two parts, and I'm actually not even sure which one came first but I don't think it matters. I was at my dad's house and taking shelter because I knew something bad was about to happen. My cousin tried to take me away from the house but I pitched a fit and jumped out of his car while it was moving and started walking back to the house. I was shown a map of the eastern United States and a red dot was placed on the westernmost part of where North Carolina and Virginia touch. This is when I realized it was going to be a meteor hit. I felt like if I stayed exactly where I was (near Charlotte, NC if it matters) that I'd be safe, and I was waiting to feel the impact but it never happened and the dream ended.

Thoughts? I'm not in any way saying I think this is going to happen, it's just strange and got my attention when I woke up and started remembering details. I almost feel like if it did happen and I never said anything to anyone, that'd be messed up yanno?
