Too much water

A young man drinks from a glass while holding a black staff in a kitchen, then the scene cuts to him sitting on a bed in a dimly lit room, reacting with shock while holding a game controller. The video loops, showing the man's reaction on a television screen, which displays the kitchen scene in black and white with the text "Drank water too fast" as he bends over, followed by the man on the bed clutching his head in disbelief.
