sleep-less/full-ness

what an odd night. i didn't sleep at all until about 5 am, which is strange because i usually sleep just fine and at length quite easily (like 10 hours+). i just laid in bed pretty much all night and at some point around 3 gave up on the total silence and boredom and watched some tv on my ipod. then, after about 5, i slept pretty well until 10:30. not sure what's up - i didn't feel well when i went to bed, so maybe it was just that. but, i thought i'd post these two pictures about sleep, in honor of my confusion.
