Reverie \Rev"er*ie\, Revery \Rev"er*y\, n.; pl. {Reveries}. [F.
   r['e]verie, fr. r[^e]ver to dream, rave, be light-headed. Cf.
   {Rave}.]
   1. A loose or irregular train of thought occurring in musing
      or mediation; deep musing; daydream. ``Rapt in nameless
      reveries.'' --Tennyson.

            When ideas float in our mind without any reflection
            or regard of the understanding, it is that which the
            French call revery, our language has scarce a name
            for it.                               --Locke.

   2. An extravagant conceit of the fancy; a vision. [R.]

            There are infinite reveries and numberless
            extravagancies pass through both [wise and foolish
            minds].                               --Addison.
