No, I don't think this dream took place in China.
I don't remember why, but I recall that I was in as hotel and that I wanted/needed to get a gunbecause there was some guy that was out to try to kill me.
I can't remember hardly any of this dream, but I remember walking around in the hotel on an upper floor when I see this little pagoda like stand where someone is selling something. I walk next to them, and notice that it's Jackie Chan. I didn't really care that it was him, or something, but I don't remember the name of what he was selling either way.
Whatever they were called, they were essentially single-use, single-shot guns, or projectile weapons.
It was basically a bolt with a nut screwed loosely on the end. The nut had gun powder and other things wrapped in paper and stuffed between the nut and bolt. You were supposed to hold it and use your fingers to push on the nut (by squeezing) which would cause the powder to ignite, and make the nut shoot off violently.
They were a dollar each.
I said no at first, and started to walk away, but then stopped and went back.
I got 10.
(this is when I watched him assemble them)
After that, I went to a hotel room, and that guy was there.
I don't remember exactly what happened, but I somehow got ahold of a Smith and Wesson .500 revolver and started shooting the guy. Somehow, the gun had like 20 rounds in it (5 round gun) and none of the rounds seem to do much to him, even though they're .50 caliber.
So...yeah
