Healing the Healers

I recently spoke with a fellow Healer who said they had felt lt a heavy weight on their chest after working on a client. I offered  to give them a long distance healing.
During the Healing I saw a grey patch on their chest. It looked like a dirty screen door that you could hardly see through. I energetically cut it into smaller and smaller pieces until it looked like grey smoke, than it just blew away.
I added white light to their chest area and it was like opening a door into a dark room on a sunny day. Very brilliant.
Later they commented how their chest felt light now.
They mentioned how they would usually filter out  clients stuff when working on them.
Perhaps their filter or screen needed cleaning.
