What does it mean to have mutiple dreams about vampires?

Dreams where a vampire is chasing you, attacking you, scaring you, or holding you. The dream is very romantic, with a handsome male vampire as the one who is doing this all to you. Realistic and vivid, as if the vampire in the dream is real.

Dreams are just random thoughts scanned in your brain while you sleep. Sometimes things you have thought or stressed about will make the dream repeat. Unless there was blood on the pillow when you woke up, I wouldn't worry about it. :-)

it means u either watched to many movies or nothing at all

Well, that sounds interesting. I know I like having dreams with an attractive guy in it. Ha...
Anywho.
The dream of vampires is usually associated with evil (but it all depends on the feelings that you got from the vampire himself.). It could mean that the tasks that you have in life are physically "sucking the life out of you", like a vampire would. Or, it could be that you feel weakened by someone else's power over you like how a vampire is more powerful than you are.
And... there's the interpretation associated not only with evil but eroticism. So... maybe you need to explore on that.

Hope that helps. :)
