The Dab Tsog is a demon in Hmong myth which they believe cause nightmares. The Dab Tsog visits a person in the night and perches on their chest, preventing them from screaming, and suffocating them to death.

It's interesting that there are so many myths of nightmare creatures throughout the world. The Mara, the Alp, the Dab Tsog. And then there is that one myth of Japanese lore of the Baku, eater of dreams, who takes away nightmares.

I suppose the myths of demons causing nightmares began because people wanted answers for what was causing these terrifying dreams.
