As with all dreams, I am not sure where it all began, but from my memory, I somehow became infected and was... a vampire. However, I was not a blood-sucking vampire. I was an age-sucking vampire, and all of us age/life-suckers were ghost-like. We could pass through objects. I was being led and taught by a more experienced vampire how to feed and stay young. To gain another person's youth and life, we would just face some part of them (usually chest) and breathe in deeply. I could sometimes see a faint smoke/fog come out of them and into me. Then, I would become younger, and they would become older. I learned if you sucked a little bit out of them they were usually ok; if you sucked too much, they would die (because you are making them become older faster). If you took somewhere in between, they would become a "vampire ghost." The life we received from people was artificial to us though, so we would have to continue taking years away from other people.
The violence entered as I encountered evil vampire-ghosts. Each of us kind of had some sort of powers that were used to kill each other. It was kind of a conquest of who could take the humans' life energy first. Some vampire-ghosts were mortal and could be killed easily. Others (including myself) were immortal; however, as contradictory as it is, we could be killed if something or someone drilled through our heads. That was the only way to kill an immortal (again, I recognize the contradiction).
So I'm fighting off vampire-ghosts who are trying to kill me while staying young by sucking life from others. I tried not to kill people; my vampire-ghost self preferred going on the middle ground. I felt that would allow them to become young again by becoming life suckers. Yet, it remained violent with huge fight scenes and the fear of not being able to trust anyone. (I'm trying to describe it without stating all of its grossness.) Basically, my power was being able to saw through people by only waving my hands and fingers. You'd have to cut them up a certain way to really kill them though... or at least slow down their ability to "come back together." The scariest parts were the kids who pretended to be all sweet and innocent but would then turn on you to take away your energy and life. They were quite evil. Some of them died in their pursuit, but I remember trying to trap one inside a slightly buried box. While it tried to fight its way out by clawing at me, I was trying to nail the box shut. I knew if it got out it would kill me. Somehow it could.
Then I kind of was removed from the scene, and I was pulling out a dvd from the dvd player. I was in my living room with friends, and I was complaining about the movie. I remember saying "What was that about? I did not put that vampire movie on my netflix. Who messed with my netflix? I did not want to see that."
I woke up shortly after that. I tried really hard to remember the details so that I could write it out later. I thought about it so much that when I re-fell asleep I started dreaming about it again. This time I was aware that for some reason I was trying to watch the sequel. I was again part of the movie, but quickly I "came out" and decided that I was not going to put myself through that. The first one was bad, and this one seemed worse. I pulled the dvd out of the player and said "that's the worse movie ever."
