Induced OBEs
Some people have attempted to develop techniques to induce OBEs:
Attempting to fall asleep without losing wakefulness. This method is generally believed to be what causes involuntary OBEs. Inventor Thomas Edison was known to use the sleep state to tackle problems while working on his inventions. He would hold a rock above a metal bucket while sitting in a chair, and let himself fall asleep. This would cause the rock to fall into the bucket and wake him up.Deliberately teetering between awake and asleep states is known to cause spontaneous trance episodes at the onset of sleep which are ultimately helpful when attempting to induce an out-of-body experience, as reported by Robert Monroe and Robert Peterson.
Deep trance and visualization. The types of visualizations vary; some common imageries used include climbing a rope to "pull out" of one's body, floating out of one's body, getting shot out of a cannon, and other similar approaches. This technique is considered hard to use for people who cannot properly relax. Common sensations can arise such as deep vibrations, impressions of very high heart rate (when it actually is in a relaxed state) and these sensations are likely to cause anxieties. A good example of such a technique consists of the popular "Golden Dawn Body of Light Technique".
Audio/visual stimulation intended to bring the subject into the appropriate state. The use of binaural beats to induce theta brain wave frequencies was observed as effective by the Monroe institute (and corroborated by others). Another popular technology uses sinusoidal wave pulses to achieve similar results. The beta/theta simultaneous brainwave patterns were also observed as effective, apparently easing the lighter sleep condition. The theta frequency is observed monitoring brains of dreaming patients, notably in REM (Rapid Eye Movement) sleep, while the beta frequency range is that of normal, relaxed awakened individuals. It is believed that one of the unsuspected powers of the drumming of the American natives during religious ceremonies caused the brain to shift among frequencies to become more receptive to the "other worlds" using similar means. See Brainwave synchronization.
Chemically induced experiences. OBEs induced with drugs are generally considered to be hallucinations (i.e., purely subjective), even by those who believe the phenomenon to be objective in general. There are several types of drugs that can initiate an OBE, primarily the dissociative hallucinogens such as ketamine, dextromethorphan (DM or DXM), and phencyclidine (PCP). It has also been reported under the influence of tryptamine psychedelics including dimethyltryptamine (DMT), and ayahuasca. Being under the influence of hallucinogenic drugs are commonly referred to as being in a psychedelic state.
Methamphetamine has also been known to cause OBEs, not in itself but through lack of sleep. It has been reported that it felt like the person was talking above and behind them and, being under the influence of the drug, had no idea what was happening.
Magnetic stimulation of the brain, as with the helmet developed by Michael Persinger.
Electrical stimulation of the brain, particularly the temporoparietal junction .
Sensory deprivation or sensory overload. Various techniques aim to cause intense disorientation of the subject by making him lose his space and time references. The first technique, attempting to fall asleep without losing consciousness, can be considered to be a passive form of sensory deprivation. The brain tends to fill in the gaps when there is nothing getting into the senses for some time. Sensory overload consists of the opposite, where the subject can for instance be rocked for a long time in a specially designed cradle, or submit to light forms of torture, to cause the brain to shut itself off from all sensory input. Both conditions tend to cause confusion and this disorientation often permits the subject to experience vivid, ethereal out-of-body experiences. This tends to happen when the subject believes he or she is in a particular position, whereas his or her actual body is either rocking in a cradle actively, or still lying down. Consciousness suddenly transfers to the mental body.
Some people who practice BDSM desire to be placed in extreme bondage (mummification) because it may allow them to have an out-of-body experience. These experiences have been reported by some people placed in extreme bondage. It is worth noting that being placed in extreme bondage is like being placed in a sensory deprivation tank, and that the OBE may be induced by the resulting sensory deprivation.
Galantamine is a Nootropic that can increase the odds of success when using along with Out-of-body experience or Lucid dream induction technique.
In some cases, extreme physical effort can induce an OBE. For example, one running in a marathon could overwork themselves and feel "extraordinarily weightless" and actually see themselves from above. Many times this is related to dehydration.
