I had similar case as thread starter. When I was at my old house, I never spoke to my Malay neighbor. it is the type of HDB units where there will only be one unit on the left and right when you come out from the lift..
they had a lot of items displaying on the potter plants, around and above, and there was once he was watering the plants and I casually ask him what are those ornaments displayed around the potted plants. he smile and said those are for protecting the household from spirits..
I told him I was shocked that he believed in such things too.. after that day, we always greet each other with a smile when we meet..
Thread Starter, why not you post a picture of the stuff you said and let other members have a look, or tell us why do you think it is those stuff that causing your career and health? I don't see how your neighbor can benefit at all if your career or health is affected thanks.
