I cannot stress how important keeping a diary of your dreams is.

For a student of psychology, or for someone who is genuinely interested about finding out more about themselves, life, everything: you will find it of Incredible Value to keep a "track record", so to speak, on the nature of the images that you're calling forth, in what way or ways you're associating them, HOW you're associating them, etc. etc.

The magician will also find this work Incredibly Valuable.
