I love sleep.
i think it gives you a break from the stress and problems of daily life a time when you can not worry about current problems.
if i had the choice between having to sleep and not getting to sleep at all i would choose having to sleep.

but if i could function normally with no sleep OR sleep just for rest or views into my subconscious i would def choose that over having to sleep to function normally.

this is because i find myself not getting enough sleep to function normally because of the ridiculous amount of schoolwork that comes with being a first year engineer (oh it'll only get worse).
