Note 81 — Chapter V
Reading edition
This explanation, based on the depth and kind of the sleep, is entirely distinct from the theory of Aliotta (Il Pensiero e la Personalità nei Sogni, 1905), who believes that dreamers differ according to their nervous type, the person of visual type assisting passively at the spectacle of his dreams, while the person of motor type takes actual part in them. I have no evidence of this, though I believe that dreams differ in accordance with the dreamer's personal type.
