Hello Vanda 
@BlessingsDeers so lovely to see you here, missed you. But understand the reasons & going to reply on your other post.
Thanks for sharing this very interesting subject. The painting is beautiful, so captures the subjects description: “Every night for a 1,000 years (500BC -500AD) sick and afflicted pilgrims flocked to the Grecian Temples of Asclepius. Healing and advice were sought during dream visitations by the ancient God of Medicine.”
Robert Moss blog article was highly informative! Throughout, it never mentions lucid dreaming, adding to my theory that non lucid dreams are just as important.
"As Ed Tick noted, the name Asklepios evokes “a tradition of holistic healing that was prized in the ancient world for two thousand years, a tradition in which dreams are regarded as epiphanies through which communication is opened between humans and divine powers.”.
"The dog, the second Asklepian animal ally, is the guide of souls and guardian of passage to the Underworld in many traditions, the friendliest of animals to man, and a primary “bridge to nature” in many lives, ancient and contemporary. "
Loved the “dog” story Robert tells.
I too have a story about a dog I use to look after. Sid a tall grey Deer Hound I’d take for walks and people use to stop & talk to us. I started noticing he would lean his body to touch the person legs or sit on their feet. People we passed, some sitting on park bench he would pull me to go to them. I’d carry on talking to the person knowing he was healing them until he moved away.

Here’s another story about Sid.
