anyway, feel free to post your dreams. if you remember any, that is.
the craziest one that i can remember happened a month or so before mothership zeta lol. my wife and i were living in the wasteland with a little group of people in something like a junk yard. some raiders broke through a wall and all hell broke loose. we escaped and found our way into a skyscraper and the door locked behind us. the interior was very complicated, and along one wall was tons and tons of doors. they all led into really small (but clean) rooms, and every room had a closet. inside every closet was a paradise. the one we opened had stairs leading down to a beach with people dancing and having a good time.
anyway, turns out we were actually on a spaceship and the ship had a GECK. all the aliens looked the same except for the leader, who for some reason was will ferrell LOL. we told him we didn't want to be there, and he started chanting "i will not live in a world with no play" over and over again. the ship took off for space and then i woke up.
it was pretty awesome.
