Contraction of Consciousness: The Phenomenology of an Neglected Feature of Psychedelic Experiences

Perhaps the most popular characterisation of psychedelic experiences is that they entail a profound ‘expansion of consciousness.’ Though this a fair characterisation in many respects (e.g., regarding the extraordinarily enhanced clarity and detail of appearances), its correlate ‘contraction of consciousness’ has received comparatively little attention. Based on a phenomenological qualitative study of 1,800 trip reports, I will detail the various ways in which psychedelics commonly induce an extraordinary concentration or reduction – i.e., ‘contraction’ – of consciousness, explicate these in terms of changes to attention, and suggest how to accordingly balance out the popular characterisation of psychedelic experiences as consciousness expanding.
