A guy on my tour told me he woke up twice during the night to see a white circle in the corner of his bedroom. 1st time he got a kitchen knife thinking someone had broken into the house and it was a flashlight, the second time some other implement of protection. No one there. A while after that he noticed his adult daughter was sleeping with her door open at night. He asked her about it, she said she kept seeing an orb (she knew what one was, if you don't, read some previous posts) in the corner of her room and it made her nervous. The house was not an old house but was built over where an old farm house had been. Sometimes it the land under the house that is haunted by spirits that linger.
