We can enter many dreams, then with a program such as Seeker or Masterfile, easily scan through them to see the frequency of dream themes. This approach to dreams—self insight through a series of dreams—is explained by Hall in The Meaning of Dreams. Important issues in our life and development occur as frequent dream themes, and are easily seen using a computer.
The program Brainstonn (Brainstorm Software Ltd) makes cross referencing dream symbols and associated comments easy. Using this program, if one dreamt of a tree and wrote one s associations, then six months later dreamt of a tree and entered this, the program instantly reminds you of the past reference to tree and can display it. Gradually a reference base of your own dreams and comments can be built up and quickly scanned. Such comparisons help to form a personality profile of yourself or others.
