Why does 12 hours of sleep make you feel so crappy?

Question

I just don’t understand, some days, usually on weekends, I’ll try and wake up after a normal amount of sleep (like 7.5-8 hours) but I feel too exhausted to wake up.

Then I’ll end up sleeping like 12 hours and I feel like crap all day. Why is this?
