Had a dream I took my pistol to a gunsmith...

Most vivid dream I've had in a while. His shop was on his ranch, west Texas style land with tanks and all. Crazy thing is, and why I'm posting, was that he was explaining the differences between all of the spring options and methods for reducing trigger resets and accuracy upgrades and all sorts of stuff I've never read about. How does this crap get into your brain? Was my brain just bullshitting me in a dream?

I remember being amazed at the knowledge of this gunsmith and although my gun was together he was showing me all of the upgraded parts he would put into it. I got to handle all the different springs and new hammer...most of which I haven't seen IRL.

Just strangely elaborate...and I remember it all, but it's funny that it's all bullshite, I don't even know where those springs go or what the combination of them would do, but apparently I have a totally convincing bullshitter gunsmith living in my head. Just surreal, and who dreams about guns?
