I know I am not afraid.This has to do with the name .I’ll look it up.They are having trouble sleeping and have no knowledge of demons but have entered a deeper prayer life.They have done that-what you suggested.
“This has to do with the name”
Couple of points..
First, you are dealing with spirits that are liars. The name they tell you is quite possibly part of their deception. I have had that happen many times.
Second, there is a hierarchy in the dark realms and they shove the lower ones out first as bait to fool you.
Third, a person usually has a wound in their soul that opens them up to the dark spirits. By following Jesus’ teachings.. forgive, pray, ..... you can receive Grace and have your soul wounds healed. Healing our soul is critically important.
The more dark spirits come around the more you must call upon Jesus in prayer and focus on God. It gets to the point where when you encounter a dark spirit you thank it for reminding you to pray.
