As I play "Spirit's Eye", I'm finding so many things that make me think the same thing, Cris53.
I grew up going to a place in Southern California called Knott's Berry Farm (near Disneyland). Some rides... but the main focus (early on) was to replicate the Old West. And part of that was a ghost town, complete with a graveyard that --after sunset-- was lit a dim, eerie green. Somewhere during my LHOD gameplay, I was 'transported' back to that time & place, and the magical, eerie feeling I got while strolling through parts of Knott's. Guess you had to be there.
Another thing I noticed in the game is that the point-of-view --when going up stairs, or down a hallway-- is very close to the ground... another effective element (of many) that adds to its eeriness. Good stuff! Thanks WRF.
