Two thoughts here.

Have you ever fell asleep and feel it was 5 mins, but your slept for 8 hours, huh. and other times felt you slept for 30 mins but felt it was 8 hours, huh. Anybody knows any ideas on this? Is this part of the time and space perceptive control.

oh shoot, i forgot the other one, it was a good one, too.

anyways, i am going to try the time thing. Whats the longest have you had? I had one where i felt it was like forever. It was when i wake up in my dream. I woke up like 50 times in my dream.(i sometimes i hate this , i get very desperate and try to wake up but only find i am still sleeping. It's like trap in a never-ending hell)
