Cataloging Dream Symbols
Anytime you notice a particularly powerful character, animal or object in a dream, write it down.
Write down what it represents for you every time it appears in a dream. Add these definitions to your dream dictionary if the entry already exists.
Notice variations in the meanings of your symbols, and in what context of dream situations do they change?
Leave space after your entry for future additions to the meanings and definitions of the symbol. Perhaps you might like to use 3x5 index cards for each entry.
Browse the dreams of your past journals, look for the same symbols and determine their meanings.
