I doser gone completely WRONG (gate of hades)

My little brother tried the idoser gate of hades because i was too scared to, and after about 15 minutes into it he started freaking out then he started balling his eyes out while he was still dosing. . but after a while he said somebody help me i turned off the camera and he ripped off the thing that was on his head and he was crying really bad i was hugging him trying to calm him down and he told me that a devil creature with horns was chasing him and pulled out a big knife and started stabbing his chest and took out his heart and held it in front of him. He only lasted 18 minutes THIS IS NOT FAKE br, br,
