The old timers say, the PUY's or shapeshifters only kill those who disrespect the wilderness.Thi
s is why there's a old Hmong saying, don't throw goats horn into the river because it choked a baby dragon once, and don't let women wah themselves in streams during their time of the month. haha

Thinking back now, I think I did spot a PUY once...a shapeshifter. I was out by myself tending some chickens at a friend's countryside home. I let out a few chickens to roam for a bit..Then all the sudden they all acted disorientedly.
..Like they couldn't see...I look up the eucalyptus trees, and I saw a Giant size bird of prey looking creature. But it was more like a Hologram, a silhouete, I saw the outlines but nothing I can confirm is physical...The best thing I can describe how it disappear is, like it just shrink into thin air....For sure it look at me, then turn to the field below, as if warning me...
Ever since, we never throw dead chickens out in the fields for the vultures...hah
a I never did, but a lot of the other guys raising chickens there did...One of them had goats too..so it could be the goat's horns that really piss off the shapeshifter..
haha
