Hey guys!

I've read some stuff about this and I never really got to know if it was true or simply rumors. So there I go:

Can a dream's time be different then real time? Is it true you could be spending one week dreaming in one night of sleep?

And if that is true, could we make time in our dreams faster/slower (whichever is the right one) to be able to spend more time lucid dreaming? I guess, it would be cool spending a whole day lucid dreaming, that way half of your life would be living fantasies and it would also be a longer amount of time to enjoy the dream world.
