Shortly before falling asleep for a short time I may have achieved some level of astral projection, or a projection of astral externalism while remaining stationary. Focused on thought and feeling rather than vision, and meditating on the idea of bondage, I imagined placing my hands into a box containing levers which when activated might be able to fit and apply cuffs to each of my wrists. without sight I then turned these levers and felt tape measures close around my wrists tightly at first, then with the mechanical loosening of an automated blood pressure reader, the tape eventually released and the box moved, at which point my eyes reactivated and the session seemed to end even though I attempted to continue the act with eyes open... the vision was not meant to last, and dreaming took over.
