Well, I have no real-world experience fighting little green reptilian aliens, either
But like I said, it was a unique experience for me. I've heard the theory that you can program your own dreams through auto-suggestion before bedtime, but it's never worked for me either.
Maybe we're all allotted one really exciting dream, and I've just had mine. Gives you something to look forward to, Frank. Let's hope yours isn't so purely frightening, though. The dream was simple and direct: Fight to the death with a thing trying to kill me. No set up, no nuance, no reasons, just kill or be killed. I'm fascinated that I had the dream, but I sure as hell didn't enjoy it.
I'd rather dream of space travel.
