Reality tunnel

From this wiki:

"The idea does not necessarily imply that there is no objective truth; rather that our access to it is mediated through our senses, experience, conditioning, prior beliefs, and other non-objective factors. [...] While it seems most people take their beliefs to correspond to the 'one true objective reality,' Robert Anton Wilson emphasizes that each person's reality tunnel is their own artistic creation, whether they realize it or not."

"Through various techniques one can break down old reality tunnels and impose new reality tunnels by removing old filters and replacing them with new ones, with new perspectives on reality—at will. This is attempted through various processes of deprogramming using neuro-linguistic programming, cybernetics, hypnosis, biofeedback devices, meditation, controlled use of hallucinogens, and forcibly acting out other reality tunnels. Thus, it is believed one's reality tunnel can be widened to take full advantage of human potential and experience reality on more positive levels."

And then there's Demetaprogramming and Metacolics Assholonymous.
