i look forward to my sleep every night. i only go to bed when i am too tired to stay up.
i never go to bed unless it is where i want to be.
when the time comes (usually at 3:00 am) when i am too tired to be bothered with anything, i wander in to my pre-warmed room and flop into bed and it is very very pleasant to drift off.
sleep provides a pleasant contrast to being awake. it is like yin and yang (? i think (i am not very smart about eastern stuff)).
pleasant feelings are promoted by "contrast".
if a person remains in one state for too long, they will become desensitized to the pleasurable aspect of it.
if you are outside on a cold day, and your fingers are cold and your nose is cold and you walk into your house that is warm, a sudden shroud of pleasure surrounds you as you say "ahhhhh that's better", and some people smile because it feels so relieving (i do (like people getting into a warm bath on a cold night)).
the "sauna" experience is an extreme contrast of swimming in an icy lake and getting thoroughly rigid with cold, and then going into the hot steamy cabin.
it feels like "paradise" until they get used to the heat. then they start to sweat and after a while it is not pleasant. they stay there until they can not take it any more, and they run out and dive into the icy lake again to get "fresh". then that is relieving to them until they get used to it, then off back into the cabin they go etc.
in the same way, sleep is so nice when i have had enough of being awake. it is the perfect compliment to my worn appreciation of wakefulness.
then, when i have had enough of being asleep and relaxed (after about 8 hours), i surge back into wakefulness, and it is fresh consciousness, because it seems "new" every day i wake up.
if i was to stay awake for all my life, i would get desensitized to being awake.
i would be like a zombie through being sick of seeing things constantly without a break.
