In many societies, dreams have been considered the gateway to another world, so the predictions received through this means were considered sacred: prophets, saints and mystics have received teachings from the gods through dreams. In the psychoanalytic school, dreams are associated with the unconscious and have a therapeutic character.

With an amazing capacity for synthesis, García Campayo analyses what lucid dreams are, what techniques are used in each culture to develop them, what they can be useful for us and what modern Western psychology contributes to their understanding.

This is the first book in Spanish where all the existing techniques for developing lucid dreams are reviewed, their effectiveness is described, a progressive planning for developing them is proposed and an exhaustive analysis is made of how they can be used for our personal growth.
