If I see someone as a black shadow, what does that mean?

It could be that an evil spirit has your ex under . Note that your mother saw him shackled and a black shadow following him. First you need to pray asking Jesus Christ to protect you and your ex-husband from all harm and danger. Next you need to talk to him and ask him if he is alright or if something is bothering him. Ask him if he feels heavy or depressed. A lot of times a demon causes persons to be overburdened with things. Next you need to ask a pastor to pray for your ex-husband. I personally believe that God is showing you that there is an evil spirit following him.
