hallucinating anxiety

A year ago, I regularly hallucinated a small black dot coming in and out of my peripheral vision. When it happened in front of my councillor, I could see this black foggy mass ball inside of them when we talked about it. They said it is what I saw inside myself.

It's as if I'm a vessel of hurt that is to be stored away and from my observations, expressed as inflection rather than projection.

Anyone else had similar experience?
