voluiscence
noun
The frustration emerges when your mind attempts to maintain focus on an elusive sensation, like staring at a shifting pattern that vanishes when given attention, or experiencing a fleeting auditory illusion that disappears upon pursuit—an unending struggle with the reflexes that resets your efforts.
Rooted in Latin 'volitans' (flying) and 'sciens' (knowing), conveying a fleeting knowledge or momentary awareness. Pronounced "voh-LOO-iss-ens"
