Books about people trapped in a single location – Horror/Sci-fi

I love stories about a group or a few people trapped and have to survive, find out what happened/where they are, and escape. Some examples I’ve read already would be The Mist and Under the Dome by King. Also the manga: the drifting classroom is great too. The crazier, the better!

Any suggestions are welcome, thanks!
