As can be seen from the entry on hypnosis, the dream process is quite amenable to suggestion and conscious influence. It is probably most helpful to think of this action as similar to the process of memory. In seeking information from memory we hold a question or idea in consciousness, the resulting associated memories or information are largely spontaneous. The question held directs what information is taken from the enormous pool of memory. A question might even call together scattered pieces of information which are then put together into a new composite, a new realisation. So the process is not only recall of existing memory, but creative. It may also access skills, such as the ability to subtract one number from another.
