A dream journal (or dream diary) is a journal in which dream experiences are recorded. A dream journal might include a record of nightly dreams, personal reflections and waking dream experiences. It is often used in the study of dreams and psychology. Dream journals are also used by people trying to lucid dream. They are also regarded as a useful catalyst for remembering dreams. The use of a dream diary was recommended by Ann Faraday in The Dream Game as an aid to memory and a way to preserve details, many of which are otherwise rapidly forgotten no matter how memorable the dream originally seemed. The very act of recording a dream can have the effect of improving future dream recall. Keeping a dream journal conditions a person to view remembering dreams as important. Traditionally, dreams have been recorded in a paper journal (as text, drawings, paintings, etc.) or via an audio recording device (as narrative, music or imitations of other auditory experiences from the dream.) Now with the internet, many sites offer the ability to create a digital dream journal.
Not so long ago, I used to record my dream. To simplify, I draw everything that i could remember about my dream every morning. I did it because of some coincidence. I wake up in the morning because of a dream. You may call it “waking dream”. But after I wake up, there is series of events that is perfectly matched with what I saw in my “waking dream”. After that coincidence, I try to draw my dream. I thought that this is a ridiculous habit. But, I changed my thought after reading some psychological books about dream journal.
