subspace
What does subspace mean?
Subspace is the altered headspace a submissive can drop into during play — floaty, fuzzy, 'like mush,' time going strange. It's driven by the body dumping endorphins and adrenaline under stress and sensation, and researchers compare it to hypnosis, deep meditation, or a runner's high. Someone deep in subspace may have a jacked-up pain tolerance, struggle to talk, and lose track of where they are — which is exactly why the top stays watching and aftercare matters. The flip side comes later as sub drop.
Origin
BDSM community term for the submissive's trance-like 'letting go' state, increasingly studied as an altered state of consciousness.
