Reality tunnel
Reality tunnel is a theory that, with a subconscious set of mental filters formed from beliefs and experiences, every individual interprets the same world differently, hence "Truth is in the eye of the beholder". It is similar to the idea of representative realism, and was coined by Timothy Leary (1920–1996). It was further expanded on by Robert Anton Wilson (1932-2007), who wrote about the idea extensively in his 1983 book Prometheus Rising. Wilson and Leary co-wrote a chapter in Leary's 1988 book Neuropolitique (a revised edition of the 1977 book Neuropolitics), in which they explained further: 

The gene-pool politics which monitor power struggles among terrestrial humanity are transcended in this info-world, i.e. seen as static, artificial charades.
