the process of assigning meaning to dreams

The Sandman is a mythical character originating in Germanic and Scandinavian folklore. He visits children in the evening, sprinkles sleep-inducing sand into their eyes and brings dreams. In the morning, the sleep sand is rubbed from the corner of the eyes.

Ibogaine is a psychoactive indole alkaloid derived from plants such as Tabernanthe iboga, characterized by hallucinogenic and oneirogenic effects. Traditionally used by Central African foragers, it has undergone controversial research for the treatment of substance use disorders. Ibogaine exhibits complex pharmacology by interacting with multiple neurotransmitter systems, notably affecting opioid, serotonin, sigma, and NMDA receptors, while its metabolite noribogaine primarily acts as a serotonin reuptake inhibitor and κ-opioid receptor agonist.

Oneiromancy () is a form of divination based upon dreams, and also uses dreams to predict the future. Oneirogen plants may also be used to produce or enhance dream-like states of consciousness. Occasionally, the dreamer feels as if they are transported to another time or place, and this is offered as evidence they are in fact providing divine information upon their return.

In Japanese culture, a is the first dream one has in the new year. Traditionally, the contents of such a dream would foretell the luck of the dreamer in the ensuing year. In Japan, the night of December 31 was often passed without sleeping, so the hatsuyume is often experienced during the night of January 1; the day after the night of the "first dream" is also known as the hatsuyume. This day is January 2 in the Gregorian calendar, but was different in the traditional Japanese calendar.

Hypnopompia (also known as hypnopompic state) is the state of consciousness leading out of sleep, a term coined by the psychical researcher Frederic Myers. Its mirror is the hypnagogic state at sleep onset; though often conflated, the two states are not identical and have a different phenomenological character. Hypnopompic and hypnagogic hallucinations are frequently accompanied by sleep paralysis, which is a state wherein one is consciously aware of one's surroundings but unable to move or speak.

Dreamwork is the exploration of the images and emotions that a dream presents and evokes. It differs from classical dream interpretation in that it does not attempt to establish a unique meaning for the dream. In this way the dream remains "alive" whereas if it has been assigned a specific meaning, it is "finished" (i.e., over and done with). Dreamworkers take the position that a dream may have a variety of meanings depending on the levels (e.g. subjective, objective) that are being explored.
