I was watching a woman being stabbed repeatedly by a man and then I was hiding up in a ceiling looking out of a spot where a tile would be and then  looking up at myself.Then I was running from the man stabbing the woman and jumped on a train while running and was really injured and laying there and the train started going really fast and there was no roof on the train,I was worried the wind was going to push me out and then I was the woman I watched being stabbed,like I was her but yet still watching her.It was a really weird dream going back and forth almost.
