Dear sister in Christ, I have read about this condition. It has a name, however, unfortunately I cannot remember the term that is applied to these night terrors. It may not be a demonic influence at all. In fact, precious case studies of this kind of experience as reported by wives who see and hear it, have revealed that the men in question were actually experiencing a very difficult fight. A fight for survival as in a war situation. Have you asked your husband what it was he was dreaming? Have you discussed this with him at all? Sometimes they remember the dream when asked or told about it, and sometimes they don't. For those husbands that can recall the dream, in every case that was studied, the man was in a horrendous battle of close personal contact with an enemy combatant. I shall pray for you and your husband, rest assured. However, please talk to him about it if you have not already; you may gain some insight into what he is experiencing. You will be in my prayers. God bless you.
