The weirdest one I can remember is I was "standing" on nothing in the middle of a seemingly endless realm that had nothing in it (aside from me and the person next to me). All I could see in every direction was the sky, which had swirls of orange, purple, green, and black in a weird pattern. I was talking to a middle-aged man, who I suspected was an older version of me from a different dimension, when suddenly he said he had to leave. Just as he disappeared, a female vampire (scary one, not "Twilight" one) appeared from my left and rushed at me ready to attack. I extended my hand in her direction, and using some sort of weird power, stopped her, disintegrated her, and then absorbed the orbs of energy left behind. I immediately felt immensely more powerful, and then the dream ended.
