I also find that my dreams come faster, are more vivid and lucidity is easier when I stay up until my body forces me to go to sleep.

I've been able to do this quite often for the past month or so, but I don't always like wasting an entire day sleeping (even if I am dreaming lucidly).

Regarding waking up from sleep paralysis, I find that I can wake up at will if I want to (it does involve what seems to be strenuous effort), but most of the time I don't want to wake up from it; I enjoy just experiencing it and seeing where it goes.
