"Hypnotic dreams have long been a method by which hypnosis is utilized in psychotherapy; however, the research on their characteristics in comparison to nocturnal dreams is sparse. Physiological correlates of hypnotic dreams have been clearly established as resembling those of a relaxed waking state much more closely than they resemble any stage of sleep (Brady & Rosner, 1966; Tart, 1964), the one exception being the observation of rapid eye movements (REM) during some hypnotic dreams (Brady & Rosner, 1966; Schiff, Bunney, & Freedman, 1961). The content of hypnotic dreams has been less methodically tested. Some psychotherapists describe using hypnotic dreams in the same manner they would nocturnal dreams and believe their content to be virtually identical (Fromm, 1965; Sacerdote, 1968; Schneck, 1953). Other authors describe having observed differences between two categories (Gill & Brenman, 1959; Tart, 1966). The most empirical articles to date have indicated some possible differences, such as hypnotic dreams being shorter, having fewer characters,having more "Alice-in-Wonderland" size distortions (Hilgard & Nowlis, 1972), and being less vivid, less fearful, and more plausible (Spanos & Ham, 1975). Tart (1966) found a correlation between depth of trance and vividness of hypnotic dreams. Some authors such as Barber (1962) and Walker (1974) assert that hypnotic dream content is identical to that of waking fantasy and quite different from nocturnal dreams. Obviously there are many contradictions in the literature of this area."

"I will try to explain a current view of dreaming and its possible functions, developed by myself and many collaborators, which we call the Contemporary Theory of Dreaming. The basic idea is as follows: activation patterns are shifting and connections are being made and unmade constantly in our brains, forming the physical basis for our minds. There is a whole continuum in the making of connections that we subsequently experience as mental functioning. At one end of the continuum is focused waking activity, such as when we are doing an arithmetic problem or chasing down a fly ball in the outfield. Here our mental functioning is focused, linear and well-bounded. When we move from focused waking to looser waking thought--reverie, daydreaming and finally dreaming--mental activity becomes less focused, looser, more global and more imagistic. Dreaming is the far end of this continuum: the state in which we make connections most loosely. Some consider this loose making of connections to be a random process, in which case dreams would be basically meaningless. The Contemporary Theory of Dreaming holds that the process is not random, however, and that it is instead guided by the emotions of the dreamer. When one clear-cut emotion is present, dreams are often very simple. Thus people who experience trauma--such as an escape from a burning building, an attack or a rape--often have a dream something like, "I was on the beach and was swept away by a tidal wave." This case is paradigmatic. It is obvious that the dreamer is not dreaming about the actual traumatic event, but is instead picturing the emotion, "I am terrified. I am overwhelmed." When the emotional state is less clear, or when there are several emotions or concerns at once, the dream becomes more complicated. We have statistics showing that such intense dreams are indeed more frequent and more intense after trauma. In fact, the intensity of the central dream imagery, which can be rated reliably, appears to be a measure of the emotional arousal of the dreamer."

"[O]verall the contemporary theory considers dreaming to be a broad making of connections guided by emotion. But is this simply something that occurs in the brain or does it have a purpose as well? Function is always very hard to prove, but the contemporary theory suggests a function based on studies of a great many people after traumatic or stressful new events. Someone who has just escaped from a fire may dream about the actual fire a few times, then may dream about being swept away by a tidal wave. Then over the next weeks the dreams gradually connect the fire and tidal wave image with other traumatic or difficult experiences the person may have had in the past. The dreams then gradually return to their more ordinary state. The dream appears to be somehow "connecting up" or "weaving in" the new material in the mind, which suggests a possible function. In the immediate sense, making these connections and tying things down diminishes the emotional disturbance or arousal. In the longer term, the traumatic material is connected with other parts of the memory systems so that it is no longer so unique or extreme--the idea being that the next time something similar or vaguely similar occurs, the connections will already be present and the event will not be quite so traumatic. This sort of function may have been more important to our ancestors, who probably experienced trauma more frequently and constantly than we (at least those of us living in the industrialized world) do at present. Thus we consider a possible (though certainly not proven) function of a dream to be weaving new material into the memory system in a way that both reduces emotional arousal and is adaptive in helping us cope with further trauma or stressful events."

"The imaginations of them that sleep, are those we call Dreams. And these also (as all other Imaginations) have been before, either totally, or by parcells in the Sense. And because in sense, the Brain, and Nerves, which are the necessary Organs of sense, are so benummed in sleep, as not easily to be moved by the action of Externall Objects, there can happen in sleep, no Imagination; and therefore no Dreame, but what proceeds from the agitation of the inward parts of mans body; which inward parts, for the connexion they have with the Brayn, and other Organs, when they be distempered, do keep the same in motion; whereby the Imaginations there formerly made, appeare as if a man were waking; saving that the Organs of Sense being now benummed, so as there is no new object, which can master and obscure them with a more vigorous impression, a Dreame must needs be more cleare, in this silence of sense, than are our waking thoughts. And hence it cometh to passe, that it is a hard matter, and by many thought impossible to distinguish exactly between Sense and Dreaming. For my part, when I consider, that in Dreames, I do not often, nor constantly think of the same Persons, Places, Objects, and Actions that I do waking; nor remember so long a trayne of coherent thoughts, Dreaming, as at other times; And because waking I often observe the absurdity of Dreames, but never dream of the absurdities of my waking Thoughts; I am well satisfied, that being awake, I know I dreame not; though when I dreame, I think my selfe awake."

"Several theories claim that dreaming is a random by-product of REM sleep physiology and that it does not serve any natural function. Phenomenal dream content, however, is not as disorganized as such views imply. The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when* compared to waking life, are underrepresented whereas others are over represented. Furthermore, dream content is consistently and powerfully modulated by certain types of waking experiences. On the basis of this evidence, I put forward the hypothesis that the biological function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance. To evaluate this hypothesis, we need to consider the original evolutionary context of dreaming and the possible traces it has left in the dream content of the present human population. In the ancestral environment human life was short and full of threats. Any behavioral advantage in dealing with highly dangerous events would have increased the probability of reproductive success. A dream-production mechanism that tends to select threatening waking events and simulate them over and over again in various combinations would have been valuable for the development and maintenance of threat-avoidance skills. Empirical evidence from normative dream content, children's dreams, recurrent dreams, nightmares, post traumatic dreams, and the dreams of hunter-gatherers indicates that our dream-production mechanisms are in fact specialized in the simulation of threatening events, and thus provides support to the threat simulation hypothesis of the function of dreaming."

"When the brain in not functioning properly during dreams of aggression, sleepwalkers have been able to commit murder. In several cases sleepwalkers did not recognize their victims. For example, one man drove 15 kilometers to his mother-in-law’s house, which means that his motor skills were intact. Then he stabbed her with a knife and did not respond to her screams. He acted as if he was under threat and initiated a fatal attack. This man had a genetic and personal history of awakening abruptly from the first cycle of sleep into a confused state and never entered REM sleep (Cartwright, 2000). The REM sleep is necessary to prevent waking hallucinations and mental illness (Siegel, 2001). Since aggression is prominent in most dreams, it is likely that our enemies cause this aggression. In a study by Hall and Van de Castle, animals and male strangers are the primary enemies in both male and female dreams. When a animal enters a dream it is almost always going to pose some threat or danger to the dreamer. The reason for this was thought to be because in ancestral times humans lived in an environment full of dangerous animals. There was also a constant threat from other humans. These ever-present dangers made behavioral strategies to avoid contact with these things and was of a high survival value. Dreaming simulates these strategies in order to maintain efficiency; otherwise, one failure to respond to these threats in waking life could mean death. Dreams are biased towards simulating threats that were common in our ancestral environment (Revonsuo, 2000)."
