Dream words

Episcopal, grandiloquent, bereft:
such words of consequence and heft
in turn, unbidden, tease my sleeping mind,
give way, at length, to others of their kind.

Loquacity, emboldening, prepense –
what mystery is this, what sense
impels such monsters to the fore?
And why am I so certain there’ll be more?

Piliferous, foretokening, mystique:
their usage scant, their prospects must seem bleak.
When I’m asleep, they quit the OED –
intrude their weighty presences on me!
