S03 E11 - I never thought I would see Evil attacking Evil !!!

This happened a few days ago. While I was lying in my bed, I thought I would check if there were any Evil Spirits hiding in my bedroom curtains. This happens quite frequently. The previous week I had seen a woman, who I believe is a Witch, was handing something to someone else in the curtains. I couldn't see what the Witch was giving to that Evil Spirit. This time when I saw the Witch, she was ready to hand something again, but this time, maybe 5 or 6 Evil Spirits came after her. This turned into some type of spinning ball of Evil. I couldn't make out what was happening, but after a few seconds the spinning ball went into the curtains and eventually into the Other Side. I never thought I would see Evil attacking Evil.
