Didn't You Hear? (1970)

Kevin is wandering through the confused haze that most college students pass through at one time or another: lectures that make little - if any - sense, pranks by the fraternities and sororities, deep yet meaningless discussions on philosophy with ones friends. Through all of this, Kevin passes in and out of a dream-like fantasy world, in which he and his friends sail a ship christened "Queen of Sheba" to a variety of islands, with natives both friendly and hostile.
