A story about a terrifying movie monster is always a pleasure, but even more so when it's true. A mummy excavated near the Valley of the Kings in Egypt is the subject of this tale. No one knows who he was in life, so his remains were labeled as "Unknown Man E." It must be frustrating to be one of the most famous mummies ever while also being completely unknown at the same time. Certain details about his burial suggested that he was a person of dishonor for some reason. Some theorize that he was a royal assassin, or at least a scapegoat for an assassination. A ruling family may have the best lives, but they also have to keep an eye out for those who want to take what they've got. But aside from speculation, Unknown Man E remains a rare example of a mummy found in an Egyptian royal burial ground that hasn't been identified. But what about the screaming part? That has a perfectly logical explanation, but not one that makes us feel better about him. Weird History lays out what we know and don't know about the screaming mummy.
