Has this ever happened to anyone?

[Jeff Barr]

Since FoRK is full of people who probably abuse their
sleep cycles as much as I do, I'd like to describe
something that happens to me occasionally and see if
it has happened to anyone else.

Basically, my normal sleep cycle is something like
5 hours. Fall asleep, dream, wake up, and find that
on average, 5 hours have gone by.

However, when I get really tired, something weird
happens and I "speed sleep". I fall asleep, have a
complete dream cycle, and wake up fully rested, only
to find that just 45 minutes have passed. I resist
the urge to get up, and manage to fall asleep again
for the rest of the night.

Is this unique or has this ever happened to you?
