A false awakening is a vivid and convincing dream about awakening from sleep, while the dreamer in reality continues to sleep. After a false awakening, subjects often dream they are performing daily morning rituals such as cooking, cleaning and eating. A subset of false awakenings, namely those in which one dreams that one has awoken from sleep that featured dreams, take on aspects of a double dream or a dream within a dream. This may be one of the causes of bed wetting, since the affected person may believe they are using a toilet.
A false awakening may occur following a dream or following a lucid dream (one in which the dreamer has been aware of dreaming). Particularly, if the false awakening follows a lucid dream, the false awakening may turn into a "pre-lucid dream", that is, one in which the dreamer may start to wonder if they are really awake and may or may not come to the correct conclusion. In a study by Harvard psychologist Deirdre Barrett, 2,000 dreams from 200 subjects were examined and it was found that false awakenings and lucidity were significantly more likely to occur within the same dream or within different dreams of the same night. False awakenings often preceded lucidity as a cue, but they could also follow the realization of lucidity, often losing it in the process.

Another type of false awakening is a continuum. In a continuum, the subject falls asleep in real life, but in the dream following, the brain simulates the subject as though they were still awake; i.e. the subject thinks he or she is still awake, but in reality, is asleep. At times the individual can perform actions unknowingly. The movie A Nightmare on Elm Street popularized this phenomenon. This phenomenon can be related to that of sleep-walking or carrying out actions in a state of unconsciousness.

Realism and unrealism
Certain aspects of life may be dramatized, or out of place in false awakenings. Things may seem wrong: details, like the painting on a wall, not being able to talk or difficulty reading (purportedly reading in lucid dreams is often difficult or impossible,) or, oddly, normal types of foods gone missing. In some experiences, the subject's senses are heightened, or changed.
Because the mind still dreams after a false awakening, there may be more than one false awakening in a single dream. Subjects may dream they wake up, eat breakfast, brush their teeth, and so on; suddenly awake again in bed (still in a dream), begin morning rituals again, awaken again, and so forth. The philosopher Bertrand Russell claimed to have experienced "about a hundred" false awakenings in succession while coming around from a general anesthetic. This is referenced in many television series like SpongeBob SquarePants.

Type 1 is the more common, in which the dreamer seems to wake up, but not necessarily in realistic surroundings, that is, not in their own bedroom. A pre-lucid dream may ensue. More commonly, dreamers will believe they have awakened, and then either wake up for real in their own bed or "fall back asleep" in the dream.
A common false awakening is a "late for work" scenario. A person may "wake up" in a typical room, with most things looking normal, and realize he or she overslept and missed the start time at work or school. Clocks, if found in the dream, will show time indicating that fact. The resulting panic is often strong enough to jar the person awake for real (much like from a nightmare). Another common Type 1 example of false awakening can result in bedwetting. In this scenario the dreamer has false awakened and while in the state of dream has performed all the traditional behaviors that precede urinating, including arising from bed, while still asleep and in bed.
The type 2 false awakening seems to be considerably less common. Green characterized it as follows:
The subject appears to wake up in a realistic manner, but to an atmosphere of suspense.[...] His surroundings may at first appear normal, and he may gradually become aware of something uncanny in the atmosphere, and perhaps of unwonted [unusual] sounds and movements. Or he may "awake" immediately to a "stressed" and "stormy" atmosphere. In either case, the end result would appear to be characterized by feelings of suspense, excitement or apprehension.
Charles McCreery drew attention to the similarity between this description and the description by the German psychopathologist Karl Jaspers (1923) of the so-called "primary delusionary experience" (a general feeling that precedes more specific delusory belief). Jaspers wrote:
Patients feel uncanny and that there is something suspicious afoot. Everything gets a new meaning. The environment is somehow different—not to a gross degree—perception is unaltered in itself but there is some change which envelops everything with a subtle, pervasive and strangely uncertain light.[...] Something seems in the air which the patient cannot account for, a distrustful, uncomfortable, uncanny tension invades him.
McCreery suggests this phenomenological similarity is not coincidental, and results from the idea that both phenomena, the Type 2 false awakening and the primary delusionary experience, are phenomena of sleep. He suggests that the primary delusionary experience, like other phenomena of psychosis such as hallucinations and secondary or specific delusions, represents an intrusion into waking consciousness of processes associated with stage 1 sleep. It is suggested that the reason for these intrusions is that the psychotic subject is in a state of hyper-arousal, a state that can lead to what Ian Oswald called "micro-sleeps" in waking life.
Subjects may also experience sleep paralysis.
In popular culture

False awakenings are sometimes used as a device in literature, and especially films, to increase "shock" effects by inducing a feeling of calm in the viewer following something disturbing.
- A twist at the end of the horror film Dead of Night (1945) is an early example of a re-occurring false awakening.
- In the first volume of Neil Gaiman's graphic novel Sandman, the newly freed Morpheus, lord of Dreams, punishes his captor, Alexander Burgess, with endless false awakening nightmares.
- In Joan Baez's "The Dream Song", the lyrics discuss a dream-within-a-dream resulting from her apparent awakening. The lyrics end "When I really woke I was frozen in between; I didn't know who I was, it was a dream inside a dream; It's all a dream."
- In the film Inception the central plot is about a man who goes into dreams to steal information. As the movie progresses the characters pull themselves into a chain of several different layers of dreams. The ending is also made to confuse the audience as to whether the central character was awake or in a stuck form of false awakening, as the film cuts to the credits before his spinning top (a "totem" to indicate whether he is dreaming or not) can topple over fully.
- In the Doctor Who episode "Amy's Choice", the series' main characters are stuck in two vivid dreams that they switch back and forth from, believing that whichever dream they're in is the real one at the time, until they switch back over to the other. This continues for the entire episode until they realize that they are both dreams and kill themselves in the dreams in order to wake up.
