You and your friends go to a museum. It's a nice and cool one, too. While walking, you and your friends see a giant skeleton on display. Your friends make fun and mock it a bit, but that's all. After you're done, you make a quick stop at the bathroom. Once you exit, you realize that the museum closed with you inside. You begin to walk around when you come back across the giant skeleton. It kinda feels a little ominous now.
