How can one person sleep so much and still feel tired?

Friday-Sunday: awake for 20 hours, sleep for 10 hours, awake for 5 hours, sleep for 4 hours, awake for 4 hours, sleep for 10 hours, awake for 6 hours... and I want to fall back asleep. I don't know if you can understand this, but that is an awful lot of messed up sleeping patterns right there.

Does this contribute to lengthy philosophical thoughts?

Does this contribute to bouts of depression?

Does this contribute to the usual procrastination?

I'm not sick, so I know I don’t have mono or anything... I just love sleeping. Is that a bad thing?
