Why can't I remember my GOOD dreams?

[Zomboid]

Oddly enough, I remembered a lot of what I dreamt a couple days ago. Freddy krueger (yes, creepy as hell when you actually dream him) kept trying to kill me and a bunch of other people and I was sick of running so I kept saying shit like "ok, just get it over with" and left myself open for some slicing, but he said he didn't want it to be that easy so I got him in a headlock and started playing his head like a bongo.

I don't have enough good dreams :/
