The title says it all really.

One night I had 3 seemingly unrelated dreams apart from the fact that I ended up on a train after being on the wrong platform a number of times. They also started off as normal dreams, a bit stressful but not nightmareish, until a few minutes (maybe more, I couldn't tell, I was asleep) before I woke up when all of a sudden there seemed to be a tremendous amount of bloodshed.

In one dream, A girls throat was cut out, another girl drowned in a bath and my husband was stabbed in the chest.
another; I had to have a hole carved at the top off my thigh in order to save mine, and another womans baby. This took place in the drivers cabin of a train.
another; I was on a underground train, it nearly toppled off the rails then 100metres ahead, the was an explosion, the rails were broken, and the train went shooting up into the air. I came hurling put of the window, thinking that when I land, this is going to really hurt. Then I realised that I had gone so high that when I started falling down, I realised I would probably die on impact with what I happened to land on. I wondered what my last words be. I started shouting my husbands name and screaming I love you, over and over again.

And this was all in one night. I have had many more about transport, mainly trains and bloodshed, since then.

Any ideas??
