In dreams, there are also other important parameters to consider, such as displacement, condensation, inversion, the shadow, etc. There are mental, astral, and even physical dreams.
Let's look at the types of dreams,
The mental dream is a product that touches all earthly concerns: love, sexuality, family, profession. It extends to the matter of time. Those who dream only in black and white should ask themselves questions. For they conjugate only in that zone. The astral dream, for its part, is a product of everything that connects us to the cosmos in a mystical communication, during which the divine gradually descends into the human and progressively erases the ego. It touches the supernatural and that which will never end; its vibrations extend into space.
The mental dream dislikes the unknown; it tries to predict by invoking symbols drawn from terrestrial experiences of the déjà vu and the déjà vécu. The mental dream brings us dull, lusterless colors, highly opaque in black and white, for it is down-to-earth, addressing nothing but the prosaic, yet it still sets in motion a wonderful machine that informs us about what pertains to the material. The rational sorting that this kind of dream provokes makes us react, for it activates the ego, provokes self-affirmation, and triggers aggressiveness in order to defend us. It takes its source in our rational deductions and daily concerns.
