I've just been having some really vivid ones lately, iono why. Some are just absolutely spectacular though. I haven't really had a nightmare since I was little, but I had one kinda close recently... though it ended up more like playing hide and seek... with huge monster thing, that wasn't really all that bad anyway... and I could change my size for some reason.... I have been having trouble remembering these things, I should keep a notebook with a pencil nearby to write them down when I wake up.
