You’re sitting in a dimly lit room just before me.  In a moment you will be hearing a sound that will chill your bones.

Imagine being buried alive, laying there in the darkness. You have no voice left to scream. Your fists hurt from pounding too much. But Now, you hear the sound of your fingernails scratching on the inside of the coffin lid.

Spectral sound puts this very sound in the ears of your volunteer, and there are no electronic devices. You use items that you have in your house already.
