Understanding our dreams is like peering through at what is just below the surface of one's own consciousness. Those hidden meanings, symbols and metaphors are keys to understanding why we make the decisions we do. They shape our perception of the world and how we see ourselves in it. I believe the Ancient Egyptians knew this because there were many dream manuals for interpretation and many copies made of dream manuals. Many dreams have been recorded and dream interpretation was open to everyone in all levels of society, not just the wealthy.
Understanding dreams was part of medical treatment and mental wellness. The Ramesside Dream Book, P. Chester Beatty, is just one of several dream manuals used by Ancient Egyptian priesthood. Please forgive the use of male pronouns. I kept to the original transliteration as much as possible.
If a man sees nomads in his dream GOOD
It means he will soon receive love from his ancestors
Belief that our ancestors are still with us, in the liminal realm and our dreams are the medium by which we can communicate with our deceased loved ones and they can reach out to us with help in our times of need. Knowing this, that we can pray to them for guidance is a belief the ancients held dear to their hearts. And it is something that we modern people should do as well.
