The mind's way of attending a meeting it never RSVP'd to.

means A state of being so absorbed by one thought or worry that it crowds out attention to everything else.

from From Latin prae- ('before') plus occupare ('to seize, take possession of') — the same root that gives us 'occupy.' So preoccupation is literally a 'pre-seizing': something has already taken hold of your mind before you even get a say in the matter.
