Didn't know ghost apparition also included TVs so i got caught by a Mariam. Good thing i was on easy learning the game and not a nightmare like I am now.
If a ghost walks over it, there is a chance it will leave it's footprint on it (Except Countlanak.) If two ghosts have similar evidence you could use it to determine if this ghost is a flying ghost or not. It is not significant until all ghosts are added.
