The weirdest unsolved mysteries you probably haven't heard before

From the Kentucky Meat Shower to Exploding Head Syndrome, these unsolved mysteries give us the creeps. Perhaps the scariest one of all is the Dyatlov Pass Incident: hikers went missing while traveling through Siberia. Their tents were ripped open ... from the inside. Some of the hiker's bodies were partially naked, but one hiker was missing more than just clothing: she was also missing her tongue!

There are many theories for these mysteries ... but nothing has been proven.
