I didn't light the fire, I just put a Fire Bottle in it seeing if I could, and damn, I hear a guy screaming, consistently too. Dunno if it is a glitch or on purpose. Also, it seems that these "occurrences" happen when our friend the Lonely horse appears hitched at the Chapel. So if you see that horse, get your video camera and head to the mansion, cause it might be a bumpy night!

AKA, she basically appears at random.

I'm still looking for that damn horse, it never seems to appear for me, every other kind does, but not this one! I'll keep updating my findings, and I'm definitely going to check out that Saloon again, its very interesting what is going on there. Probably the three best things I have found are the Ghost Chicken, the Fireplace Ghost, and those self-fixing items. Overall, it seems Tumbleweed does have some paranormal AI in it, or some really great glitches.
