I had an experience with the subject of spiritual warfare almost exactly like you describe in your book. A number of years ago, I led a small women's Bible study at my workplace and one day prayed rather vigorously against any demonic forces, etc. involved in a workplace issue. I assumed that everyone understood what I intended. Not so. One member reported me to her supervisor and I ended up with some explaining to do.

It sounds like the demon slapped you with its tail on its way out the door.
