On Dreams (Unabridged‪)‬

"On Dreams" appears in Aristotle's Parva Naturalia. He examines questions like whether dreams pertain to the faculty of thought or to that of sense-perception. In part two, he considers the circumstances of sleep and the operation of the sense organs operate. In part three he attempts to explain how dreams arise, suggesting that it is the residual movements of the sensory organs that originate them.
