1) I'm a raccoon. Groot is a tree. We are best friends. 2) Pete, at this point in the dream, is a bounty. I'm trying to catch him because I want money. 3) Gamora and Pete are fighting while I am trying to catch Pete, and therefore Gamora is also fighting me and Groot. 4) Not a Western, but I have a badass gun.
Weird thing is, schematics for said gun have popped into my head after I used it. It's of my own design. Seems dream me and real me share a love for things that go boom.
