Cognitive disconnection is the experience of feeling distant and detached from one's sense of identity, thought stream, and general cognitive processes. This may lead to or be complemented by other effects, such as depersonalization, derealization, memory suppression, "ego death", and a general array of cognitive suppressions. The experience of this can also create a wide range of subjective changes to a person's perception of their own consciousness. These are described and documented in the list below:
- Feeling as though one's conscious thought stream and memories are not one's own
- Feeling as if one's conscious thought processes are distant and vague
- Feeling as if one's conscious thought processes have become autonomous and mechanical in their structure or behaviour
- Feeling a decrease in the overall speed, connectivity, and analytical abilities of one's cognitive abilities
Cognitive disconnection is often accompanied by other coinciding effects, such as visual disconnection and physical disconnection. This results in the sensation that one is partially or completely detaching from both their sensory input and their conscious faculties. It is a near-universal effect under the influence of moderate dosages of dissociative compounds, such as ketamine, PCP, and DXM.
