hey. Sage works. Have a neighbor who fancies he is a healer of sorts. He isn't terribly friendly but offered to cleanse our house out of the clear blue. We still have our sweet little ghost but the poltergeist are gone. He also did a personal cleansing with burnt feathers and sage and identified a health issue I have, but have never discussed, Sometimes one needs to suspend disbelief. Old homes come with residual energy. I know of five cremains on our property but who knows what else?
