Watch Facing the Truth

A 2002 fantasy film which features the residents of the dreams of Jeff Brooks. It shows how they occupy themselves both when he is dreaming and while he is awake. One resident is Milo, who takes the form of various flying creatures in a recurring series of dreams Jeff has nightly. Milo takes time to document Jeff's activities and what he sees throughout the day, so he can incorporate those things in his dreams later on. Jeff takes it upon himself to organize the residents into specific sub-categories and documents the cataloging process extensively.
