worst dream?...

I've personally always had very vivid dreams even as a child, especially nightmares. Mainly when I was younger I would have a specific nightmare that plagued me once or twice a month. The weird thing was after the first time of experiencing it, the following times I knew it was a dream and I already knew what was going to happen and I would try and change it. Which, surprisingly worked. I guess it was more of lucid dreaming? Not too sure. Anyways, I don't remember the dream so much any more but I do remember a part of it. I would like, walk into this decrepit like house, supposedly where I lived, and I would go into this one room where my mother would be. Only, she wasn't really my mother. It was very strange. I would then leave the room, because she really freaked me out and I felt something wasn't right, and then I'd hear her screaming. I'd go back in and she'd be in the process of melting. Like, her felsh melting. Yeah, pretty screwed up. XD; But I think that was probably the worst dream I've had, even if it was a really long time ago. Either that or my frequent plane-crashing-whilst-I'm-in it, type dreams. I will say, car crash dreams sound really frightening. I've never had one, but I had a dream that came close to being one.
