Fast shadows, running, Voices, Knocking;

A group was in the basement fireplace room, when they saw a fast, dark shadow flash past the windows.

While in the piano room, a woman's voice said the name of the tour guide. 3 people heard this.

Knocking that started on the floor above, then in the room next to us.

In the basement, the flashlight kept turning on, and off yet no one was within 10 feet of them.

Small feet, running in the halls above us was heard several times.
