===Mechanical induction===
* [[Brainwave synchronization]] via audio/visual stimulation. [[Binaural beats]] can be used to induce specific [[Neural oscillation|brainwave]] frequencies,<ref name="Sadigh">{{cite web|url= https://www.hemi-sync.com/hemi-sync-technology/research-papers-articles/the-effects-of-hemi-sync-on-electrocortical-activity-a-review-of-three-empirical-studies/ |title=The Effects of Hemi-Sync® on Electrocortical Activity: A Review of Three Empirical Studies |first1=M.

Binaural induction of a "body asleep" 4 Hertz brainwave frequency was observed as effective by the [[Monroe Institute]],<ref>{{cite book|last=Campbell |first=Thomas |year=2007 |title=My Big TOE |url=https://archive.org/details/mybigtoeawakenin00camp |url-access=limited |pages=[https://archive.org/details/mybigtoeawakenin00camp/page/n75 75], 79 |publisher=Lightning Strike Books |isbn=978-0-9725094-6-6}}</ref> and some authors consider binaural beats to be significantly supportive of OBE initiation when used in conjunction with other techniques.<ref>{{cite book|last=Buhlman |first=William |year=2001 |title=The Secret of the Soul |page=198 |publisher=Harper Collins |isbn=978-0-06-251671-8}}</ref><ref>{{cite book|last=Bruce |first=Robert |year=2009 |title=Astral Dynamics: The Complete Book of Out-of-Body Experiences |page=164 |publisher=Hampton Roads Publishing Company |isbn=978-1-57174-616-0}}</ref> Simultaneous introduction of "mind awake" beta frequencies (detectable in the brains of normal, relaxed awakened individuals) was also observed as constructive. Another popular technology uses sinusoidal wave pulses to achieve similar results, and the drumming accompanying Native American religious ceremonies is also believed to have heightened receptivity to "other worlds" through brainwave entrainment mechanisms.<ref>Haven, Janine.

* Electrical stimulation of the [[brain]], particularly the [[temporoparietal junction]] (see Blanke study below).
* [[Sensory deprivation]]. This approach aims to induce intense disorientation by removal of space and time references. Flotation tanks or [[pink noise]] played through headphones are often employed for this purpose.<ref>Nicholls, Graham. (2012). ''Navigating the Out-of-Body Experience: Radical New Techniques''. Llewellyn Publications. {{ISBN|978-0738727615}}</ref>
* [[Sensory overload]], the opposite of [[sensory deprivation]]. The subject can for instance be rocked for a long time in a specially designed [[Bassinet|cradle]], or submitted 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.<ref name="Irwin, Harvey 1985">Irwin, Harvey. (1985).
