What do people projecting negativity feel if the “Repel Negativity” audio is playing?

I’m thinking back to a time I was chillin’ in my living room and my housemates were around. I had “repel negativity” playing because the negativity was strong and I didn’t want to lose focus on my task.

I live with energy healers of various levels of moral code (and lack of). The person I had the most challenge with, I suppose was being repelled because as he sat at the table I felt him sloppily attacking me and pushing back, as if i was the source. I had to work on my solar plexus to clear the attack.

Im curious what he might have felt from the audio. I’ve read a few stories here about others who experienced kickback from the audios being used. If you’ve been on that other side, what did it feel like?
