The meaning of memory in dream | Dream Interpretation
Penfield’s experiments with memory, along with the experiential side of humanistic psychology, suggest that most if not all of Our experiences are retained in a level of memory we seldom have access to. Our everyday experience of accessing pans of our memory, and only occasionally touching other pans, is an example of this. Even prenatal life has been shown to leave memory, although it is not verbal.
The word unconscious can refer to the memories which we have little access to, or have not been able to recall since their inception, but which can be recalled under special circumstances.
To dream about a memory, suggests that you are ready to rid yourself of your old ways and undergo some sort of transformation, gaining a new outlook in life. Recalling a memory in your dream indicates that you have learned something important from your past.
Loss of Memory in a dream presages a rise in the world shortly.
