A Weird Dream I had

This is what I remember:
The boy was tied up and stuffed in a bag. It was clear he had been raped or otherwise used as a sex toy, basically. Paraphernalia was around him and on him even. I was with someone else during the discovery and horrified, the only one disturbed by it, I think. I went upstairs and found an old cap-and-ball revolver, but I either couldn’t find caps and ammo or just couldn’t figure it out. Then I noticed a wooden toy gun and picked it up. I don’t remember if a person (not the rapist) saw me and figured out what I was gonna do with it or if the rapist saw me first. I’m leaning more towards the former, so I shall tell it that way: I palmed the gun and pimp-slapped the person so hard that they fell to the ground and the toy split in two. Then the rapist came down. He was an old man, somewhat decrepit. I started beating him with it. I knocked him onto the floor with a pistol-whip, and then I started punching him with the pistol. The last thing I remember was attacking his foot for some reason. Either my attacks were weak or he was too far gone mentally because he was sorta laughing and didn’t resist.
