This is very normal.
I was in a restaurant with my wife having dinner, when suddenly both my legs were in excruciating pain. I looked around and saw that a guy in a wheelchair at the next table was a double amputee.
I was feeling his phantom leg pain.
When this happens, saying a prayer for the person diminishes my pain.
I feel viruses as a separate consciousness from the person they occupy. They feel like I am reaching into a big swarm of gnats. I’ve said this for many years prior to Covid.
It is especially true with Covid. It is stronger and denser than most viruses.
“I was feeling his phantom leg pain.”
I could see this happening. It has never happened to me personally though.
