I was Jonny Lee Miller and I was solving a murder in London (been watching a bit too much Elementary, perhaps...) where all the victims were killed in different ways, had nothing in common, but all had the word "HECUBA" carved into their faces. I figured out that it was a reference to the bit in Hamlet where he's talking about the players and says "What's Hecuba to him, or he to Hecuba?" and it turned out the murderer was an actor having a sort of psychotic break and was murdering people according to the way certain characters died in plays because of some sort of compulsion that made him think that was the only way he could act properly. So like one guy got killed with a poison stab wound like Hamlet, one woman was smothered by a pillow like Desdemona, he made someone crash his car into a tree like Willy Loman and made it look like an accident, he disemboweled a guy like in M. Butterfly and made it look like he'd done it to himself, just fucking loads of them. I didn't even know my subconscious *knew* that much about people dying in plays.
Anyway, I figured it out and then the guy came after me and drugged me so that I would be his captive audience while he acted out his favourite bits of plays and stuff. He wasn't very good, but it was very very scary. I kept waking up and having sleep paralysis where I couldn't remember what was real and what wasn't, and every time I went back to sleep it picked up in the same spot of the dream so I was convinced that I needed to solve the crime and get free. Scary.
