I live in a spiritualist community. What you are experiencing is a really thing. Smudging is a way of bandaging the issue temporarily. This spirit may not necessarily be evil, you just may be a sensitive and you are experiencing the pain or emotions of the spirit that is in your house. There are several paths you can take to remove the spirit from your home. Everything is based on intention. So when you are smudging for the time being make sure you have nothing but love in your mind and soul. You can also contact a spiritual reverend, they will come to your home and cleanse it for no charge. Depending on your location, I could help you find someone if this is something you choose to do.
