I had this dream back when I had to wake up early on a consistent basis. The context is that im in this all glass two story room that is somewhat like the lobby in jurassic park one where they hide on the bones from dinosaurs in the end, with about 20 other people. Out side there is about 10 feet of cement and then the "tall grass" from jurassic park two so I know if I try to leave they would kill me. There is an Identical glass room next to ours that we can see in to which contains another 20 or so random people. A floating hologram of a saw like charcter appears and tells us that "once we kill it, it will end" A polar bear appears in the other room and starts mauling and killing every one as they frantically try to run from it. As we finish watching every one die in the second room the saw like charcter reappears and restates "if you kill it, it will end" A tiger then enters our room, but we band together to try and kill it. Im able to get the tiger in to a headlock and one of my friends slips a pillow case over its head. I start banging its head against the hard ground. On my third attempt I heard a sickening crack/crunch instantly follwed by BEEP!BEEP!BEEP! my alarm clock...
