Dream books

A dream book is an oneiromantic tool which is formatted as a sort of dictionary listing different things which might appear in a dream alongside their symbolic meanings. These were popular over a long period of time, and on several occasions were used as miscellanea for other divinatory books.

Entries are often sorted alphabetically, but also may be sorted by element, category of thing (birds, beasts, objects, etc), or by sign of the Zodiac.
