Song/ Chant from dream last night “ The Circle of Light can’t be broken”

Last night I had a dream that really bothered me. I was attending an outside event, and decided to leave the gathering. I found myself in the sitting area of an amphitheater upon leaving the gathering. Slowly a group of people (5-7 groups of people) formed a large circle around me and were chanting in a sing song style “The circle of Light can not be Broken” I knew none of the people, and woke up after about 7 verses. It has bothered me all day.

Any idea of what this might mean or what it is trying to tell me?
