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. It was further expanded on by Robert Anton Wilson, who wrote about the idea extensively in his 1983 book Prometheus Rising.
Except that some people have a problem grasping objective truths, such as the categorical imperative being a good guiding principle.
