The Essene Gospel of Peace is an ancient manuscript attributed to the Essene community. The manuscript is said to have been kept in the secret libraries of the Vatican and a first translation of it was finally made available to the public in 1928. It is divided into four books filled with the customs, practices, and way of life of the Essene brotherhood. The following excerpt is taken from Book 1, where Jesus explains the process of learning during sleep:
“And God will send you each morning the angel of sunshine to wake you from your sleep. Therefore, obey your Heavenly Father’s summons, and lie not idle in your beds, for the angels of air and water await you already without. And labor all day long with the angels of the Earthly Mother that you may come to know them and their works ever more and more well. But when the sun is set, and your Heavenly Father sends you his most precious angel, sleep, then take your rest, and be all the night with the angel of sleep. And then will your Heavenly Father send you his unknown angels, that they may be with you the livelong night. And the Heavenly Father’s unknown angels will teach you many things concerning the kingdom of God, even as the angels that you know of the Earthly Mother, instruct you in the things of her kingdom. For I tell you truly, you will be every night the guests of the kingdom of your Heavenly Father, if you do his commandments. And when you wake up upon the morrow, you will feel in you the power of the unknown angels. And your Heavenly Father will send them to you every night, that they may build your spirit, even as every day the Earthly Mother sends you her angels, that they may build your body. For I tell you truly, if in the daytime your Earthly Mother folds you in her arms, and in the night the Heavenly Father breathes his kiss upon you, then will the Sons of Men become the Sons of God.”

As the text says, various spiritual beings (or your own Being) can instruct and teach in your dreams. Therefore, when waking, don’t move at all, but rather, try to remember your dreams: what you saw, where you were, what was happening, and so on. See how it fits within the context of your life, and try to use it to help with your daily spiritual practice in general.
