A spirit waived to me when I left the Morse Mill Hotel!

Last night I had to take supplies to the hotel. I was putting a trash can in the bathroom of the prostitute room and I had the door closed, I could hear foot steps in the hallway then coming into the room leading right up to the bathroom door. When I checked there was no one there! Later on that night I had to go to the bathroom and from the light coming through the doors on both sides of the hallway I could see the outline of about a dozen people standing in the hallway but I knew I was alone! I always say hi to the spirits, and bye to them when I leave. When I was leaving and put my stuff in the car and I turned back around to look at the hotel through the window in the front door I could see a woman's hand sticking out of a long blue sleeve like a dress waiving to me! It was completely solid like a real person, but only lasted a few seconds.
