Dream map
It is a process that can be done in group even if it is basically individual.
The result of this process will be the creation of a Dream Map, which is not a drawing and not a map commonly intended. It will be a map that comes from subconscious and talks to the subconscious, a sort of reminder created by unconscious mind for its own benefit.
It can be practiced by everyone, literate or not, experienced or not but must be guided by trained guides.
Dream mapping starts individually and once practiced it can switch to the groups.
