==== Proposition 1 ==== Dream experience embodies an “organized and selective simulation of the perceptual world.” Sensory modalities are fully integrated into perceptual dream experience, and the “active dream self” has a body image similar to that of the waking self in the “visuo-spatial world.” Dreams are composed of interactions that mimic archetypical wake-state experiences and situations with people and objects. Revonsuo states that dreams are the result of an “active and organized process rather than a passive by-product of disorganized activation.” The predicable organization of dreams renders them as more than “random noise”; rather, he views their function as a “selective simulation of the world.”
==== Proposition 2 ==== Representations of daily life experiences are absent while dreaming. Dreamers experience a “selective simulation of the world” biased towards threatening situations. The high proportion of negative emotions experienced while dreaming correlates to the need for “adaptive responses that increase the ability to respond appropriately in adaptively important situations” (Revonsuo, 2000). The misfortunes and aggression experienced in a dream state may act as a simulation that prepares the dreamer in the case that a similar situation may occur in the awake state. Evidence lies in the activation during REM sleep across regions that are necessary for the production of these emotionally charged experiences.
==== Proposition 3 ==== Real waking life experiences that are traumatic to the individual causes the dream-production system to create dream content that simulates responses to threats as a mechanism to "mark situations critical for physical survival and reproductive success." Revonsuo writes that "what from a psychological point of view is a 'traumatic experience' is, from a biological point of view, an instance of threat perception and threat-avoidance behavior."
==== Proposition 4 ==== The threatening dream content, while not an accurate depiction of one's real-time experience, seems incredibly realistic and is therefore effective and productive practice for threat-avoidance responses. He postulates that there is proof of this proposition in that dreamed action is consistent with real motor behavior and that "dreaming about an action is an identical process for cortical motor areas as actually carrying out the same action."
==== Proposition 5 ==== The perceptual and motor skills simulated in dreams will increase the efficiency of an individual's performance of those skills even if the dreams are not explicitly remembered. Studies have shown that the implicit learning of skills that are important for human performance can be learned and actualized without any conscious memory of having learned them. Furthermore, Revonsuo writes that "REM sleep physiology appears to selectively support implicit, procedural learning."
==== Proposition 6 ==== The threat-simulation system "was selected for during our evolutionary history," implying that it was not innate but rather came to be in response to the multitude of threats experienced by human ancestral populations. These populations lived in a "more or less constant post-traumatic state" and the dreaming brain constructed the threat-simulation technique as an evolutionary tool, resulting in improved threat-avoidance skills and, thus, a higher probability of survival.
