Re: I have a dream. (and MAN was it wierd!)
It's been a while, but I've been having this recurring theme in my dreams.
At first, things seem "normal", but then little "puffs" of gossamer stuff (like little clumps of spiderweb or dandelion fluff) starts descending from the sky. Whenever it get's wet, it activates and begins converting whatever living matter it touches into an alien life form. Somehow I am immune, and although I keep trying to warn people to watch out for the stuff, eventually, people become infected.
People don't change physically, but they become part of the hive mind that is the invading ecosystem, and start hunting down the "unprocessed" so they can become integrated with the hive mind. At some point in the dream, I begin skipping backwards in time to counter the invasion, but with limited success. Sometimes I discover the way to stop the invasion, while in other dreams I can't figure out how to stop it from happening.
The last time I had this dream, I kept trying to stop the invasion, but the hive-mind people captured me. I convinced the hive-mind not to kill me because I could time travel, and was therefore a valuable resource. My intent was to wait until I could time travel again (it comes and goes) and leap backwards far enough to enlist the help of scientists to develop a defense against the invasion.
