when someone is highly anticipating something that is to occur the next morning; but to reach that morning they first must sleep through the night, resulting in their waking several hours earlier than normal. sometimes trouble falling asleep out of excitement is associated with this effect.
often experienced by children on christmas morning, teenagers on hopeful snow days, and adult males the night before their hot date with the girl in 6c.
