Spatial disorientation
Spatial disorientation is the failure to perceive or perceiving incorrectly the position, motion, or altitude of oneself within the fixed coordinate system provided by the surface of the Earth and the gravitational vertical. It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as diphenidine, ketamine, and DXM.
Spatial disorientation is the failure to perceive or perceiving incorrectly the position, motion, or altitude of oneself1 within the fixed coordinate system provided by the surface of the Earth and the gravitational vertical.2 In this state, a person may have trouble distinguishing up from down, right from left, or any two different directions from another. The person might also perceive the world or their own body as being flipped sideways or upside down.
Spatial disorientation is often accompanied by other coinciding effects such as holes, spaces and voids, changes in felt gravity3, and dizziness.4 It is most commonly induced under the influence of moderate dosages of dissociative compounds, such as diphenidine,4 ketamine,5 and DXM.
