Understanding Altered States of Consciousness, (ASC):

Altered states of consciousness:

Altered States of Consciousness (ASCs) are mental states that differ significantly from ordinary waking awareness. They can occur spontaneously, be induced intentionally, or result from physiological/psychological conditions. In an ASC, a person’s perception, sense of self, time awareness, emotions, and thought processes may shift noticeably.

Common Features

  • Changes in perception (visual, auditory, or bodily distortions)
  • Altered sense of time (time speeding up, slowing down, or losing track of it)
  • Enhanced or reduced self-awareness (ego-dissolution, heightened introspection)
  • Emotional shifts (euphoria, fear, detachment, bliss)
  • Different thought patterns (fluid, symbolic, dreamlike, or hyper-logical)

Examples of Altered States

Natural states

  • Dreaming (REM sleep, lucid dreaming)
  • Daydreaming
  • Hypnagogic/hypnopompic states (between waking and sleep)

Induced states

  • Hypnosis
  • Meditation (mindfulness, transcendental states, Zen absorption)
  • Trance states (shamanic journeys, religious ecstasy, possession trance)
  • Flow state (deep absorption in activity)

Substance-related states

  • Deadly Psychoactive drugs (psychedelics, dissociatives, stimulants, depressants)
  • Alcohol or other intoxicants

Physiological or extreme conditions

  • Sensory deprivation/overload
  • Near-death experiences
  • Extreme fasting, pain, or sleep deprivation

Theories & Uses

  • Psychology: Studied for understanding consciousness, creativity, trauma, and mental health.
  • Therapeutic use: Hypnosis, meditation, and psychedelic-assisted therapy show promise in treating PTSD, depression, and addiction.
  • Spiritual/Religious: Many traditions see ASCs as paths to enlightenment, healing, or connection with the divine.
  • Neuroscience: ASCs involve measurable shifts in brainwave activity (alpha, theta, gamma states) and neurochemical changes.
