1 Introduction
Altered state of consciousness



An altered state of consciousness (ASC), it describes induced changes in one's mental state, almost always temporary. A synonymous phrase is "altered state of awareness".

It can be associated with artistic creativity.


An altered state of consciousness can come about accidentally through, for example, fever, infections such as meningitis, sleep deprivation, fasting, oxygen deprivation , nitrogen narcosis (deep diving), psychosis, temporal lobe epilepsy or a traumatic accident.


An ASC can sometimes be reached intentionally by the use of sensory deprivation, an isolation tank, sleep deprivation, lucid dreaming, hypnosis, meditation, prayer, or disciplines (e.g. Mantra Meditation, Yoga, Sufism, dream yoga, or Surat Shabda Yoga ).

ASCs can also be attained through the ingestion of psychoactive drugs such as alcohol and opiates, but more commonly with traditional hallucinogens of indigenous cultures, plants such as cannabis , psilocybin mushrooms, peyote, ayahuasca, or datura (though less common and incredibly more lethal). Other modern hallucinogens that some attempt to use for a similar purpose are (D)-methorphan , Salvia divinorum, LSD-25 , substituted phenethylamines , substituted tryptamines , and substituted amphetamines such as those listed in the books PiHKAL and TiHKAL by Dr. Alexander Shlugin, a former forensic and analytical organic chemist of the Drug Enforcement Administration. These drugs are often noted as " designer drugs" by authorities and professionals or as " research chemicals" by the hallucinogen-use and distribution underground, as an attempt to avoid prosecution under the Federal Analogue Act.

Another effective way to induce an altered state of consciousness is using a variety of neurotechnology such as psychoacoustics, binaural beats, light and sound stimulation , cranial electrotherapy stimulation, etc.; these methods attempt to induce specific brainwave patterns, and a particular altered state of consciousness.
