Play on words.
Play with words.
One word leads to another and our amazing mind wanders (wonders) through a maze.
Obtuse, obscure, observe, obverse, adverse, advertise, seek, sneak, snuck, snooze
fascinating, facilitating, facility, faculty, faculties, tease, trees, sneeze, snooze
vacillating, vacuum, cumulating, cumulus, stratus, status
Your mind can wander aimlessly connecting the dots.
