Bottom line, don't mess with those things
Last year, I took an outing to Glacier Peak Wilderness (in Sauk Indian dialect it is Lushootseed or "Tda-ko-buh-ba")
Hiked up the Suiattle River drainage and pitched a tent around 4,200 feet, all alone no other hikers/campers. Settled in for the night and everything seemed to be going to plan. Fire built and dinner was cooked. Late that evening is when SHTF, it started with what sounded like a grown man crying or howling. This shit was echoing off the canyon walls and scary as fuck. Sounds of approaching footfall followed
I immediately got up, reached for my pack, and realized someone (my cunt cousin) had left a OUIJA board in there from a prior trip. Packed everything up in 15 min, threw that thing in the fire and GTFO in a hurry, back to the trailhead by daybreak
Never going back up there again
