I was staying for a week in this old hotel in Nashville TN on business. The Hermitage Hotel. It is rumored to be haunted but I did not have time to do any paranormal work until Halloween Night, the night before I was leaving to come home.
I turned on my Sangean DT200X and walked around and then settled at the foot of the bed. As I was asking if something was stopping them from crossing over I heard the plate from my nightstand fly off and hit the ground near me. I felt it hit.
After that you hear responses such as "Satan" - "Leave Him Alone" - and "Warning"
