Stages of sleep through different brain waves

Brain wave patterns constantly change when sleeping, and these different patterns don't just tell a how deeply that person is fallen in to sleep but how effective suggestion can be absorbed within a clinical environment.

hypnagogic state is the point between sleep and being awake and this is where you are very aware of you're surroundings around you. Hypnagogic brain wave can be described as the point you feel just before falling into sleep which is where you are at your most susceptible and is also called the alpha brain wave.  Alpha brain state is the brain wave young children are suppose to be permanently in until the age of around 5 this is the reason why they remember and repeat everything you say.

Once a person falls into alpha sleep that person can then drift into Theta which is a heavier sleep and is know to state you dream in. Theta is the deep sleep  stage but not the deepist and it is still very much possible to take in and collate information through this brain wave.

Delta  brain wave is the deep sleep and is known as Rem sleep. It is unusual to go into this type of level of sleep though even at this level you are still able to take in certain commands and information.

Brainwave frequencies and associated states of the mind.

  • 20Hz + (Gamma) This is a high level of arousal, e.g. when facing a perceived danger or threat. Subjective time is often slowed down when the brain is operating in this fast state.
  • 15Hz-20Hz (Beta) Normal focused awareness. Associated with conversation, complex tasks and problem solving.
  • 9Hz-14Hz (Alpha) Relaxed but aware, light meditation or hypnogogic state. Associated with suggestibility, increased learning ability and neurochemical changes.
  • 5Hz-8Hz (Theta) Deep relaxation, light sleep. Associated with deep meditative states and flashes of inspiration.
  • 0.5Hz-4Hz (Delta) Deep sleep/unconsciousness.

Hypnotherapy & the sleep state

A hypnopompic state (or hypnopomp) is the state of consciousness leading out of sleep, a term coined by the psychical researcher Frederic Myers. Its twin is the hypnagogic state at sleep onset; though often conflated, the two states are not identical.

The hypnagogic state is rational waking cognition trying to make sense of non-linear images and associations; the hypnopompic state is emotional and credulous dreaming cognition trying to make sense of real world stolidity. They have a different phenomenological character. Depressed frontal lobe function in the first few minutes after waking – known as "sleep inertia" – causes slowed reaction time and impaired short-term memory. Sleepers often wake confused, or speak without making sense, a phenomenon the psychologist Peter McKeller calls "hypnopompic speech". When the awakening occurs out of rapid (REM) sleep, in which most dreams occur, the hypnopompic state is sometimes accompanied by lingering vivid imagery. Some of the creative insights attributed to dreams actually happen in this moment of awakening from REM. In Deirdre Barrett's The Committee of Sleep, Margie Profet's McArthur-award winning biology experiment is shown to be one of these.
