A long and detailed dream from like a week and a half ago. I had like half of it typed out in here but I lost it.
In the beginning, my brother and I were Sam and Dean Winchester from Supernatural (I was Sam), we worked for the SCP Foundation, and we were at the wedding of Sansa Stark from Game of Thrones. My brain must have had some trouble with the setting creation.
The wedding took place on the sloped front lawn of some fancy mansion. I was in love with Sansa so I was sad to see her get married, but my brother didn't care as much. We were here primarily on business, and he was excavating a large cube-shaped chest out near the front of the lawn. Eventually he got it all the way out and called me over.
We opened it and inside was smaller box that was filled with water and contained a plastic pen. I immediately concluded that the water-filled box was a containment device of some sort and breaking it would have really bad effects. So we take it to my apartment where my brother tells me to hold on to it until we can deliver it to the Foundation.
Someone immediately drops it and breaks the box.
As it fell, I concluded the pen must cause a huge explosion whenever it touched anything that wasn't water. The box shattered, the pen flew out and hit the floor, and nothing exploded. Good thing I was wrong. My brother and I stopped being Sam and Dean around this point.
My brother left to go do something while I stayed to watch the pen. Eventually some water near it started to boil off without being hot, so I found out the pen's real effect: any time it was stationary, it created a slowly expanding field around it that lowered the boiling point of water drastically. I had to keep it moving.
Luckily I had somewhere to go. I got in my car, threw the pen in my back seat, and went to pick a couple people up to head to a party. It was two girls I know, but I no longer remember exactly who they were. They got in the back. At some point I turned onto a main road and remembered that the pen's effects could be lethal, so I leaned back and grabbed the pen and threw it up onto my dashboard. The girls were very confused since they didn't know the thing's effects.
Then I started wondering about how it worked. I realized it couldn't just be based off being absolutely stationary, because the earth itself was never stationary. So it must require an unchanging velocity to start having effects. Exactly like the velocity of my car.
At this point I noticed it was raining quite heavily and there were puddles everywhere. A van was driving over one near me, and suddenly the puddle exploded like a geyser and launched the van into the air. It happened to a couple more cars, then it happened to mine. Luckily for me, my car landed right side up so I kept driving. My passengers understandably started freaking out, and eventually another geyser launched my car up. It landed on its wheels again.
I knew I wasn't going to be so lucky next time, so I kissed my job at the Foundation goodbye and threw the pen out the car window. The rest of the drive was uneventful.
The party happened to be a high school sort of slumber party. There were a ton of people there, laying down in chairs and on beds and on couches. I think I was the only person moving around besides an adult chaperone or two. I found my brother at some point and I think I talked to him about smoking weed. No dream-weed was smoked, though.
Eventually I settled onto a couch with my ex girlfriend and a couple dudes from high school. It was a reclining couch in front of the TV. After a bit, they all pushed me off. Then everyone at the party started having sex under the covers. Luckily there weren't many details there that I need to leave out, it was just a thing that was happening and I was pretty pissed that I was getting excluded.
Then I woke up.
Interestingly, I had an episode of sleep paralysis that night. There are two possibilities of when: the first is that I woke up after I threw the pen out the window, had the sleep paralysis, then fell back asleep and dreamed of the party. The second is that I woke up at the very end of the dream and had it. I can't remember which, but I know it was one of the two.
