No. 7 is "7. Involuntary Neurological Response to Latent Stimulus: Putting this into English; you have 5 senses that are much more sensitive than we expect. Our 5 senses work in concert to give our brain information about our immediate surroundings. Sometimes this information is inaccurate and can put pictures or sounds in our heads that are not there. A faint change in room temperature, humidity, a faint odor, or a familiar sound can light up parts of your brain."
The ghosts stories that make me sure there is something actually out there and it is not our senses include this one which a friend related about her youth.
Her family lived in a large house that at one time had been a nunnery. During building work, a large cupboard/box room was found. It only ever had a door into it, no window and that door had been covered over with wood panelling.
A door was reinstated and the room was used as a small study. One Christmas, due to the number of guests, a camp bed was put into the room and one of the children visiting was given the room to sleep in.
The next day the child was found asleep on a couch in another room. He said that during the night a lady had asked him to move there as he could not sleep in that room. He was unfazed, but the adults were rather put out. All denied it was any of them.
Go on a few days and new guests and this time my friend's uncle was given the room. The next morning and he was found asleep on the couch. He to related that he had been woken by a lady who had asked him to move, which he had done and like the child he was happy to comply, at the time....but now he was rather freaked out and that room was never used for anyone to sleep in again.
