Spirit of fear.
Many years ago I had a job guarding an office building. The company had recently moved. One night I looked in a closet. No good reason. Well, there was a huge plush on there. It was weird looking, but OK. That should off been the end of it. But afterwards I started seeing it out of the corner of my eye. Reason told me that's silly but it kept happing. Then one Sunday night our church had a guest speaker. He spoke on unclean spirits and how they try to get at us. When mentioned a spirit of fear I was like DUHHHH. I knew about this stuff. But the attack on me started so sneaky I had thought it my imagination.
My next night at work I went straight to the closet opened it and there it was. But it didn't look weird. It knew what I was going to do and tried to hide. Then I called down the holy ghost and kicked it off the property in Jesus name. Not preaching. Just relaying my haunted doll story.
