What's up with my gory, disgusting dreams?

I've had really disgusting dreams lately. I am not a morbid person by any means, but lately I've had very gory dreams. I dream about blood, dismembered body parts, bloody injuries and accidents... I had a dream that I was applying for a job at a human slaughter house, and there was body parts and maggots everywhere. I also had a dream that I was riding one of those trains at an amusement park and it took us through barbed wire and everyone got all sliced up. WTF?? This is definately not me.. I wake up wanting to throw up!!
