killing my boyfriend?

Date: 3/25/2017

I guess in this dream I had a boyfriend who was abusive.. I made out with him close to the train tracks of a train headed our way and just as it got to us, I pushed him down and killed him... I felt relieved that he wouldn't hurt me anymore. but I felt scared that someone might've seen. second dream: I had another boyfriend(maybe the same one) who was trying to kill me. we were in a human sized hamster maze of tunnels and I was crawling through it trying to escape him. Only he created the tunnels and he new his was around way better than me. I woke up before he could catch me though. third dream: I don't remember why but I was very content and pleased about something that had happened...
