What is the meaning in a dream of vampires

I was being chased and eventually caught by three vampires that resembled my wife and two kids. I was unwilling to defend myself and woke up as I was bitten.

I was being chased by vampires on a train

I was with my ex-boyfriend and his daughter at a playground, when he started acting crazy, so I drove away but I still had his daughter's coat, bag and car seat in my car. I worried she would be cold and was annoyed at my ex boyfriend for not being worried. Later I was in a giant school, cafeteria in England where my new boyfriend, one I had never met, was with me telling me how to get away from vampires, we were big chased by vampires and there were other people with us who kept getting killed by the vampires. We finally reached the cafeteria where we were safe but I tried to buy lunch and the lady behind the register kept getting angry at me and people were still being killed by the vampires.
