In a firsthand submission to HauntedPlaces.org, a Warehouse operator describes a young girl floating at the end of a hallway. She reportedly reappeared during demolition and floor work, watching briefly before fading. The same account mentions door sensors activating in a sequence that suggested someone moving through the building.
Footsteps seem to follow people through the Wisconsin Historical Society's headquarters, and unseen hands are said to send books to the floor. A submission to HauntedPlaces.org associates the disturbances with two former occupants, including a man who died at his desk. The identity and death stories remain uncorroborated lore.
