Dream 1 - House Party
In my flat house, my flatmate has decided to throw a party to celebrate the end of exams. I'm not really interested in the party and I just decide to chill out in my room, but I have to go get the door at some point because no one else was. I peer outside to see a group of people, I see a couple familiar faces, and tell them to come on in. As they walk in I get a better look at their faces, I make eye contact with one and think 'hmm that looks R'... Then look away kind of puzzled. Then I go 'oh shit! That's R!', we look back at each other suddenly and we get ready for some fisticuffs. Everyone in the party is a little shocked that a fight suddenly broke out.

Dream 2 - Crime Scene
I'm walking along at night with a couple friends, some guy who punched me at a party earlier on in the night (I forgot this part of the dream) ran up to us from the liquor store across the road. He wasn't trying to start a fight this time though, he had a white shirt and blues jeans, a pimply face and blonde curly hair. We all end up having to run because someone starts chasing us. We run up a hill and as I reach the top of the hill I see police, they're gathered around a crime scene. Headless bodies lie scattered about, blood is everywhere, part of me is stunned, the other part is intrigued. Even the police are flabbergasted, they don't even know what to say to us, so I ask an officer about the crime. "Someone reenacted a portion of the story from the Dragon Play that's playing in the city".
Basically to summarize this play, a person kills all the guests that enter his house because they sin whenever they enter the premises of another persons home or something, and then there's a dragon in it at one point.
I head to the city to try and track down the culprit, determined to end his/her brutal killing spree. I was armed with the knowledge that it might likely be multiple people, since the heads of the people had be severed simultaneously and all by the same blade in one clean slice. An idea popped into my head at this point that was something along the lines of gunpowder powered guillotine that could cut off the heads of multiple people in one sweep. Imagine multiple head + hand locking things stacked on each other, each person is separated by a plank they can lie on. Then the guillotine is let loose and is propelled through all their necks by the force of the gunpowder. I kind of woke up at this point debating if that even made sense or if it actually existed.
