..first of all, I'm finding it hard to distinguish between the "newb" and "general" sections, but I guess I'd post in the newb section when I'm asking questions that have definitely been covered, or something that would be in an "intro" tutorial.

Anyway, I've heard a bunch of accounts of dreams that feel very long in a short real time, or feel very short in a long real time, and we've probably all experienced that. My question is, has anybody actually experimented with that and tried to make a dream seem longer or shorter? It would be pretty useful (didn't some guy report having a dream that lasted 100 years? Man, it would be hard to get back to normal life once you woke up)
