Reality Tunnel
A reality tunnel refers to an individual's unique perception of reality, shaped by personal filters and cognitive biases. These "tunnels" are reinforced by confirmation bias, where we focus on information that supports our preexisting beliefs while ignoring or rationalizing away anything that contradicts them.
This self-reinforcing process makes reality tunnels largely invisible to their inhabitants, creating the illusion that their perspective is objective. While many people assume their beliefs align with "one true reality," each person's reality tunnel is a subjective creation, shaped by their own thoughts and experiences, whether they realize it or not.
It is believed that through the use of psychedelics one can break down old reality tunnels and impose new reality tunnels by removing old filters and replacing them with new ones creating new perspectives on reality.
