I've seen this in a deep meditation I had a couple of years ago. It was a very strange occurance where it felt like I was connecting with an entity for communication. I remember sitting upright and my body/head started to move in this pattern. As this was happening it was like i/we were tuning like a radio. Intertwining like a dance m, every so often the connection would become stronger and I could almost hear the thoughts being relayed. They were very faint and I got the feeling the transmission was from very far away. I was eager to connect as was the other end of the line. We both tried and tried but couldn't quite make a direct connection. Whenever I see this depiction it always reminds me of that instant.
