Cognitive disconnection can be described as the experience of feeling distant and detached from one's sense of identity, thought stream and general cognitive processes. This leads into states such as depersonalisation, derealisation, 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 reality has become distant and vague
- Feeling as though reality is a film or a dream
- Feeling as though the world beyond one's immediate external environment is simply non-existent
- Feeling a decrease in the overall speed, connectivity and analytical abilities of one's cognitive abilities
- Feeling as though one's conscious thought stream and memories are not one's own
Cognitive disconnection is nearly universal under the influence of dissociative compounds such as ketamine, MXE and DXM. The state it induces is also often complemented by the simultaneous experience of tactile disconnection and visual disconnection, resulting in the sensation that one is partially or completely detaching from both their sensory input and their conscious faculties.
