Am I Dreaming?

Every night, Tripitaka's sleep is disturbed by a recurring dream. In it, he's being attacked by Lord Yuki, ruler of The Devil's Hell. One night, after Tripitaka nearly sleepwalks off a cliff, the disciples decide they must take immediate action. They think up ways of expelling the demon from Tripitaka's body. Things don't quite go to plan though - before long, Tripitaka ends up in very hot water, and Monkey gets pulled into the dream too...
