There are a good number in the demo and the haunt system chooses them and runs them based on your actions. So there is a good chance you did not see them all. There’s often something right behind you that if you don’t see it, will be removed and re-cycle back into the system for later use. If you re-play, the experience will be different. Not HUGELY different in the demo but in the full game it will be different story events, hauntings, bodies, and demon.
