Late at night or earlier morring I see a full black
Body figure in my room and in the door way!
I have also experience glass coasters that I have
On my window cell to hold my curtains down go
Flying off the window cell! What is black shadows?
What causes them to come into a home? How do
You get rid of them?

Shadows are not a "type" of spirit. They are simply a manifestation of a spirit. They can take many forms and cause many things to happen.

Since I shadow person is not a certain kind of spirit... there are many reasons that a spirit may be in your home. MANY reasons.

The only authority they are absolutely bound to is that of Jesus Christ. Some spirit entities are stronger than others, and you can even describe them as a military unit, where some are OVER others in power and authority... but ALL of them are subject to the name of Jesus.

I suggest you speak to a pastor (one that understands this area of study).
