Like, super late post on this one.
I don't remember a lot of the dream, but it was along the lines of the zombie facility one, where I was in some underground facility, with zombies (but maybe this one didn't have zombies, but normal people. I think maybe normal people in this one).
I had a Smith and Wesson .500, or what I perceived as one. If you don't know what that is, it's basically a 5-round revolver that does just devastating damage to pretty much anything you shoot at. For some reason, it had really small bullets though, like they were three centimeters long, but as thick as a .50 cal round (handgun .50 cal).
Somehow I got to a relatively big room, and there was someone I was shooting at, and I think they were shooting at me. In this dream, I had psychokinesis, like I do in a few of my other dreams (and as usual, it was hard to control, and weak).
But this time I used it a little differently.
Once I ran out of ammo, I opened the gun (to expose the revolving portion) and flicked it backwards, ejecting the empty rounds from the gun (also I may note that it opened in the style of Vash the Stampede's revolver, where the entire gun folded forward to expose the revolving portion). I reached into my pocket, which had hundreds of bullets in it, and grabbed a handful. I tossed them into the air in front of me, and used my psychokinesis to hold them in the air, and manipulate them all to load into the gun, which I held below them. Loading them one at a time was a little strenuous.
Because, well, my dreams like to be 'realistic' with these things. I had to concentrate on ALL of it, to make it work. They loaded in, and the remaining shells I let drop onto the ground.
Stuff happens, and for some reason, I go to have my gun hover in the air. Like, I just let go of it so I can do something, and I tried to keep it floating in the air, which worked mostly.
One of the times I loaded the gun with the psychokinesis, I accidentally tugged at the little pin/flint/whatever the hell is tapped to make the bullet go off, and made it slide out the back a little by accident, which made me freak out a little, since I thought the bullet was going to explode in my face.
Either way
This part of the dream was pretty cool, and I think the rest of it was as well, thought I can't remember it.
