Perception of predeterminism
Perception of predeterminism can be described as the sensation that all physical and mental processes are the result of prior causes, that every event and choice is an inevitable outcome that could not have happened differently, and that all of reality is a complex causal chain that can be traced back to the beginning of time. This is accompanied by the absence of the feeling that a person's decision-making processes and general cognitive faculties inherently possess "free will”. This sudden change in perspective causes the person to feel as if their personal choices, physical actions, and individual personality traits have always been completely predetermined by prior causes and are, therefore, outside of their conscious control. During this state, a person begins to feel as if their decisions arise from a complex set of internally stored, pre-programmed, and completely autonomous, instant electrochemical responses to perceived sensory input. These sensations are often interpreted as somehow disproving the concept of free will, as the experience of this effect feels as if it is fundamentally incompatible with the notion of being self-determined. This state can also lead a person to the conclusion that their very identity and selfhood are the cumulative results of their biology and past experiences. Once the effect begins to wear off, a person will often return to their everyday feelings of freedom and independence. Despite this, however, they will often retain realizations regarding what is often interpreted as a profound insight into the apparent illusory nature of free will. Perception of predeterminism is often accompanied by other coinciding effects such as ego death and physical autonomy. It is most commonly induced under the influence of heavy dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
