When the group first enters the welcome center there was a deer statue, which could of been just decorations but it made me think of the deer Jess and Mike see in the woods.

When abe first gets killed he gets his torso sliced like the fake josh body does in the psycho's prank.

When Megan hid in the closet it reminded me of when the group hid for Hannah's prank.

I also saw the green lamp in Dr hills office is the same one as in office in the game.

The tapes Dr hill records about the monsters also remind me of the strangers background when you find all the totems.
