Movie-esque dream? Yep, had one.
It started in my university class where I was alone with few random students, and one began acting jiggly and giddy. So we sprayed him with water and he partially melted, partially exploded because he was the changeling of sorts. We then watched news on the subject of recent changeling revolt or something of that kind. Then I had to avoid changelings from unviersity to my house because they turned you with touch and were vulnerable to water.
At home, my mother recommended me using a pain-soothing gel because it's mostly water + some compounds that further weaken the changelings. So I applied some to myself.
Then I was outside and was battling few of my neighbours who were changed, and arrived in my university to deliver a lecture of 'Living in Harmony and Avoiding Accidental Turning' to the changelings because the government believed we can live in peace.
Of course, the speech was written by some gov.worker, so it was utterly boring and kinda insulting, but I don't remember the text. I did see and read the text, though. The changelings were giving us a chance and so I was supposed to speak with one of their high-ranking officials of sorts, who lived in a manor. That changeling turned out to look exactly like Ciel from The Black Butler anime, just an adult. On the way to basement, where he wanted to show me his human slaves living in 'happiness and harmony' with him, I decided I won't have anything of it so I shot him from my water rifle in the face, causing him to explode messily.
Of course it meant I forever destroyed any chance for peace between humans and changelings, so I decided to storm the changeling HQ before they learn of my treachery. Equipped in two water-filled rifles, I stormed local kindegarten - the place were changelings were hiding.
There, I had to kill my changed sister and her girlfriend, two girls from my university, some of my cousins and uncles, then some random people, and even managed to kill few changelings that, during the beginning of the massacre, turned into furniture and tried to ambush me. I believe I killed ~30 changelings before water in my rifles ran out. Then I was accosted by Ivan.
Ivan was a russian changeling and he was very resistant, and he looked exactly like Guardian G.I. on one of his newest photos; dark short hair, black formal suit, dark demonic eyes. He ran after me, and the last spurts of water from rifles did only scorch him slightly. I believed it was time to use my secondary weapon - the 'grenade', which was my name for Hydrogen Peroxide (H2O2) filled jar.
And just as I smashed said 'grenade' against Ivan's head... my mother woke me up, because I overslept my alarm clock by 20 minutes.
