I've seen my fair share of spirits. Most recently I have seen an abundance of them after declaring that my home was home to any spirit. I am also part Native American but I am Ojibwa.
In most cases where a spirit is in my personal space I just say get out or so. When I was little I guess I befriended a powerful spirit. He helps me when it's needed.
Most spirits will listen to you if you are uncomfortable with their approach. Anyways I put a forum up just a second ago about this spirit that seems to always be nearby. See if you can help me figure out my spirit and I'll try to help if I can about dealing with spirits.
