In Whitley Strieber's book, The Key, the visitor claims that the carvings depict soul container technology.
Maybe these carvings at Dendera might be worth exploring with remote viewing.
"...To use souls as tools. Look at the carvings at Dendera in Egypt. Those strange objects in the containers are not electrical filaments or religious symbols. Those are souls.
The walls of the containers bear an electrical charge of a type that imprisons them.
Because of the use of such technology, elemental bodies extended their
perception outside of the time stream, with the result that the school of the earth ceased to work as a place of change.
The human soul is imprisoned?
It is imprisoned.
Will this ever end?
Your enemy does not want it to end. They fear you too much. When you see UFOs, you see prison guards.
They also act within your society to confuse you about your own past, and to prevent progress in areas such as propulsion, which might enable you to spread into the heavens. This is all done to prevent you from escaping.
Who is this enemy?
You know them by many names. But you yourself had the privilege of meeting your enemy face-to-face.
Was I in the company of demons or aliens on that night in 1985?
Remember that the air is never so sweet, nor thy wife so comely, nor thy child so beautiful, as after the battle won. We depend upon our enemy for the sweetness of our lives.
Love your enemy, for he is your best friend. Without the darkness, you would never know the glory of the firmament.
We are in chains, just as you said. But you also said you had the key.
This whole conversation is the key. You should bless your jailers, because without them you could never find your freedom.
When you, as a species, remember why you have been imprisoned, and you face what you did, you will be free.
What did we do?
I can tell you plainly. But you will not believe me, not in your hearts. Your hearts are in denial.
Listen well, because this is the first time the true story of the taking of the fruit of the tree of knowledge has been said since you left the garden.
You went to war against God. You fought the deepest meaning of the universe, in quest of what you thought you were missing. Greed drove you to seek this knowledge, which is knowledge of yourselves separate from God.
You imagined that being surrendered to God was being enslaved by God. You did not see giving oneself to us is the only true freedom. It is not that man is the servant of God, but that man is God, as are we all.
There was an actual, physical battle?
There is a sacred science. It enables complete mastery of time and space. You had access to this science and used technology based on it.
You went to war. This whole solar system bears scars from the battle, some of them terrible. You remember this, because you fought.
I don’t remember a thing.
Your species bears a wound in its soul that makes you deny the reality of the past that is plainly visible all around you.
Mars was murdered by you. At that point, intervention occurred, as it will again when you destroy this planet, as will probably happen.
This is the trigger for intervention, the destruction of a living world."
