Labrie wanted to not be a jock and not live each day just like the last. Then he must have realized that partying everyday like its the last is better. Then we wakes up from catatonic sleep, which he slept in for 30 years. Then he is falling back into sleep. During sleep, he has a bunch of visions, realizing that you must do righteous things and have a sense of guilt, and that the world always works how it did in the past, good things are rewarded, bad are punished. And he probably goes to hell for the stuff he did while he was alive. That's my interpretation.
