Don't Sleep.

In the heart of Bangkok, a group of friends is unknowingly drawn into a deadly game with an ancient and malevolent spirit. After a tragic accident, Thai, a guilt-ridden biker, struggles with sleepless nights and haunting visions of a young boy he hit in a hit-and-run. Desperate for peace, Thai turns to his friend Tle, who leads him to the mysterious Mhom, a medium who specialises in dark rituals and the occult. Mhom introduces them to the Phi Thuai Kaew, a cursed Ouija board that supposedly holds the key to lifting Thai's curse.
