And I'll close with a high level story spoiler which you should stop reading if you want to avoid, but I'd like to have known going in… The story is mostly and broadly based on a combination of Macbeth and the Paisley Witch Trials. Reading a little about each will give some insight to what the characters of Sleep No More are doing, which otherwise would require many viewings to resolve into a coherent understanding.
