well it's not impossible to have a dream seem to last for longer than it really is. It's all about perception. But there aren't any real techniques for doing so. it just has to come about by chance. Like others, i've had dreams that seemed to last hours but when I wake up, it really hasn't been that long. people say that when a dream seems to last for an entire day, it's just because it's like in a movie where it skips from scene to scene. You kind of skip from place to place in your dream, which makes it seem like an entire day, even though you didn't really dream about the entire day... er... night. but who cares, eh? i mean, lucid dreaming is pretty much just about the way things seem. If it seems real... if it seems to last a long time... if you seemed to be flying when your real self was laying asleep in bed. Who cares if the time doesn't really last that long... at least it seemed that way, which is good enough.

sorry... i'm totally ranting.
