Was she any good other than talking about the cleansing? If it matters, my vote is no, no and No. $500??
A long time ago I had a psychic tell me about some negative energy around me mumbo, jumbo, so I went to my go to psychic and asked her about it. She said she didn't see anything like that around me. I tried a local once when I was in GA and she tried the same thing so I told her that technique won’t work on me and that I’ve heard it before. It's an old gimmick psychics use to milk you out of money. If they don't seem that psychic and tend to give you generalities, you can't really expect them to be any good at cleansing, can you? Apparently if the reader has to resort to this type of bologna, sometimes it means they aren’t getting enough money. It doesn’t mean they aren’t gifted; you just have to get the conniving reader back on track.
I've run across this too with Keen readers. Initially, I read with one who was good and affordable, but then later on, tried to tell me to get some healing meditation from her. I blocked her and never talked to her again and left her a scathing review. It's not worth it, no matter what they say and especially if you think there is something negative around you. It's not true!
