If I was something out of the nature of humanity in that way to not be in a need of sleep, I would appreciate the experience of life with wide opened eyes 24 hours a day but for now I love my dreams and nightmares! ZZZzzzzz....I might try to keep out the fourth day awake but in the end I wont be choosing. I'll be sleeping at the first place where my body says "stop torturing me" and runs away from me into a sleep.
