Unlike the waking state, the brain cannot recognize its own condition; that it is in the midst of the dream and is not the same as the real world. [1] The brain has a single-minded state of primary consciousness during dreaming, which allows the brain to reach greater perception and awareness of a single scenario out of images and dreams. [1]
This includes the activation synthesis theory—the theory that dreams result from brain stem activation during REM sleep; the continual activation theory—the theory that dreaming is a result of activation and synthesis but dreams and REM sleep are controlled by different structures in the brain; and dreams as excitations of long-term memory ...

[1] Humans spend about two hours dreaming per night, [2] and each dream lasts around 5–20 minutes, although the dreamer may perceive the dream as being much longer than this. [3]
Research into dreams includes exploration of the mechanisms of dreaming, the influences on dreaming, and disorders linked to dreaming. Work in oneirology overlaps with neurology and can vary from quantifying dreams to analyzing brain waves during dreaming, to studying the effects of drugs and neurotransmitters on sleeping or dreaming.
Related to—yet distinct from—the manifest content, the latent content of the dream is the unconscious thoughts, drives, and desires that lie behind the dream as it appears. These thoughts in their raw form are permanently barred from consciousness by the mechanism of repression, but continue to exert pressure in the direction of consciousness.

Conversely, dreams can evoke past events, both known and unknown to the subject.

The term often implies either a lifelong socially monogamous relationship or a stage of mating interaction in socially monogamous species. It is sometimes used in reference to human relationships.
