Bad Dream

I had a dream I was in a house and there was giant blood sucking bugs that were trying to get me.

Then it changed and I was outside in the country with some people and there was a town that seemed empty, there was a forest beside it with graves and we went over to have a look then some female vampires flew out of the graves into the sky, they were screaming and wailing while flying around.

We all ran back to the town and it was dark, one guy drove away in his car and 4 of us went inside a building then it was like a horror move, we were trapped inside while the vampires stalked us.

We were all looking around the building, one of us went upstairs on his own like an idiot and we couldnt find him then I looked out the window it was pitch black and cold outside then one of the vampires saw us and we freaked out and ran away.

Then a weird looking old lady appeared and I thought it was the vampires messing with us and I had a gun all of a sudden so I loaded it and tried to fire 3 times but nothing happened then she turned into a vampire and got me.

I woke up after that to a dark cloudy day and everything feels different like my life has changed somehow. What does it all mean?
