In the above comments I was not putting any blame on you. I was trying to say that maybe you have an ability, and that ability may have attracted some negative forces. You may be like a magnet which draws the negative. Sometimes people have certain sensitive abilities in which they are not aware of or not able to control.
If we are dealing with darker forces of the first order than you need intervention from someone from an established church. You may wish to contact one of your local churches.
Dealing with demons is very tricky. They have an ability to appear as spirits of the deceased, or use the deceased in their schemes. They may take on animal forms. If the name of the demon or demons is known than one has power over them and can drive them out. In order to battle them you need to be in the company of the clergy. People can battle them on their own, but it takes great faith in the Lord. You can call on the Holy Spirit for guidance in the interim.
During my attempts to reach out in my own way to read your situation I detected something blocking me. I could not determine if it were human or otherwise.
I do detect that you have a great inner strength that you can muster. You have an innate ability. I pray that God grants you the ability to overcome this evil and that He will protect you and your home.
