transience
Moments in time, moments evoking the senses or our memories. Something that we can’t put a finger on exactly: a vague recollection, a dissipating trail of a scent, or a dreamt scene that doesn’t make sense and leaves us puzzled about the seen imagery. Or, to the contrary: a sharp, clear, but short-lived physical, mental, or psychic event that, in spite of its duration, stays with us for a long time.
A juxtaposition of the uncertainty of interpretation to active manifestation.
