'''There are specific demonstrations which can be carried out that can show the public altered conscious states similar to the [[Psychedelics|psychedelic]] experience, commonly known as ''replications'''''. These ''replications'' are publicly demonstrated at the [[Fundamentals of Psychedelics]] lecture series. | |||

Specific optical illusions can demonstrate some of the visual effects experienced | Specific [[Optical Illusions|optical illusions]] can demonstrate some of the visual effects experienced during the psychedelic experience. Most notably static pictures becoming animated. A quick example of this is illustrated in Figure 1. | ||

A bright light which flashes at the same speed as the transmission rate of the optical nerve can induce visual [[hallucinations]] similar to effects induced by psychedelic substances<ref>'''Altered states phenomena induced by visual flicker light stimulation'''. Marie Therese Bartossek, Johanna Kemmerer, Timo Torsten Schmidt. Published: July 1, 2021. https://doi.org/10.1371/journal.pone.0253779</ref>. This effect is called [[stroboscopics]]. | |||

An ordinary mirror will show you your reflection as you see it everyday. Double mirrors or "''flip mirror''" or "''true mirror''" shows you as others see you - a view you rarely get. As your face is is most likely not perfectly symmetrical it can feel as if someone else is staring back at you. | |||

Psychedelics such as [[ketamine]] act dissociatively, causing [[Out of Body Experiences|out of body experiences]] (OBE). By using stereoscopic cameras and a virtual reality headset a phantom self experience can be felt (see '''Figure 2''')<ref>'''The experimental induction of out-of-body experiences. Science''', Ehrsson, H.H. 317: 1048, first published in 2007. Accessed on 18th October 2022 via: http://www.ehrssonlab.se/pdfs/Ehrsson-Science-2007-with-SOM.pdf</ref>. | |||

OBE effects show how the patient can feel as if they are leaving their body, Astral projection is then the feeling of re-embodiment within another. By using the same apparatus as listed above, the camera is then focused on an actor mimicking the actions of the primary viewer<ref>'''The Machine To Be Another'''.
