 The head, being constantly asleep, must always be dreaming, otherwise it will wake up and throw the brain into confusion; as there is no body for it to be attached to .The job of a dream composer is to "play" the head's "dream organ" in order to purchase a map of the head's interior so that he may find his way out.Insanity (a plan of whose was thwarted previously by Bluebear) steals the map, but right before Bluebear is pushed into the Lake of Oblivion, a pool of liquid forgetfulness that totally annihilates anything thrown in, 1600H pushes Insanity into the lake himself.
