reverie

A state of dreaming while awake; a loose or irregular train of thought; musing or meditation; daydream.

If you rouse from your reverie, you are restless and agitated; your eye wanders round in one perpetual search; and if, perchance, as has happened once or twice, he has only passed in the distance, your eye brightens, your cheek flushes crimson, and your whole frame quivers with uncontrollable emotion!

we sat / But spoke not, rapt in nameless reverie, […]

An extravagant conceit of the imagination; a vision.

If the minds of men were laid open, we should see but little difference between that of the wise man and that of the fool; There are infinite reveries , numberless extravagancies , and a perpetual train of vanities , which pass through both .

To daydream.

By this time the mouth begins to feel uneasy—I pick another cheroot from Cotton’s last box, and walk up and down reverie-ing as before.

So now the dream of all my life is realized, and I have seen snow mountains! When I was quite a little child of eight years old I used to reverie about them, and when I heard the name of the snow-covered Sierra de la Summa Paz (perfect peace) the idea was completed; and I thenceforth always thought of eternal snow and perfect peace together, and longed to see the one and drink in the other.

A caper, a frolic; merriment.
