ALTERED STATE OF CONSCIOUSNESS I: Introduction
One of the most powerful states and motivators in impact play is the "pain high." It's closely related to subspace, though the pain high carries an added layer: the neurochemistry triggered by pain itself. Both belong under the broader umbrella of altered states of consciousness — a shift out of ordinary waking awareness into a state where thought quiets, sensation sharpens, and the usual noise of the mind falls away. That shift is precisely what makes impact play so compelling: it's not just about the pain itself, but the door it opens to somewhere else entirely.
Charles Tart, a foundational figure in the psychology of consciousness, defined altered states as
“a qualitative alteration in the overall pattern of mental functioning […] that is radically different from the ordinary” (1972).
What makes a state "altered" is not simply that it's unusual, but that it reorganizes how sensory input, memory, identity, emotion, and self-awareness are processed and experienced.
The same category includes things people already recognize: the “tunnel-focus” of a runner's flow state, the way grief can make a Tuesday afternoon feel unreal, or a two-hour session feel like a good half-an-hour. What ties them together isn't the trigger — it's that something in the perception of reality has shifted.
Duration stops being tracked the way it normally does. When I’m “high” even as top (via the mirror neurons) I can’t process and calculate numbers on a digital watch and I can’t count the strokes of a cane. It isn't "being bad at math" because I’m very well able to do these cognitive tasks when I’m not high. It's a specific feature of altered states: high-level cognitive functioning, such as numeric processing go offline when the brain shifts into this mode. The way we process reality changes.
For people who reach this through impact play, that shift tends to show up in a few specific ways:
Time gets slippery. Duration stops being tracked the way it normally is. Sessions and scenes that lasted 2 hours can feel like half an hour; scenes that lasted five can feel endless.
The edges of the body blur. Where skin ends and the outside world begins can stop feeling fixed. Some people describe warmth spreading past where they were actually struck, or it feels as if the entire body region was hit all of a sudden, not just the upper back.
Words land differently. A simple instruction — breathe, count, look at me — can carry a weight it wouldn't carry in ordinary conversation. This is heightened suggestibility, a well-documented feature of altered states generally.
Control feels optional. The sense of being the one steering the moment — deciding, evaluating, narrating — can fade. This is often described as surrender, but it’s more precisely described as a loss of agency.
