I've often felt that my dreams (or even thoughts during a normal awake state) do not necessarily apply to time.

For some reason it seems as if I can think very very fast (as in between sentences of talking to people while I'm awake, I'll be about a couple of paragraphs of though). And in dreams, I've had ones that seem ridiculously long.

But the dream bit may be just that all of your other dreams are relatively shorter.
EDIT:
The awake thing may just be that I am insane.
