23 hours
Fell asleep on the couch watching a show and woke up the next day to the same show - kind of freaked me out at first.
... I ended up taping aluminum foil over the windows in my room and slept an average of 14 hours a day. For a year.
Was this to keep the aliens from reading your mind while you were asleep and defenseless? If they could have read your mind/dreams, would they have been amused or horrified?
I'm surprised at the teenagers being allowed to sleep longer than 24 hours. I'd e waking my kid up and checking on them!
