I don't know if it's Vegas or what, but I had a slew of crazy dreams last night.
Some of them were long and disjointed while others were fairly linear (although strange), but sandwiched inbetween them was this very short misfiring of the neurons...
I was standing in some kind of a huge hall with a group of people and, of course, one of H. R. Giger's aliens (as in: like the one from the movie "Alien").
This one was different, though. It had a human brain strapped to the top of its head, and this brain was green.
Another thing that was odd about this alien: it was laughing. If you can imagine one of these horrors of horrors smiling, then that's what this thing was doing.
I was talking to it; telling it jokes. It was loving them. Everything I said was the funniest thing in the universe to this alien. It tipped its head back and howled with laughter.
One of the people standing with us said, "He thinks you're pretty funny" and "He seems to really like you."
As soon as he said this, things went south. The alien's brain exploded in a chunky wet mist of brain parts flying in every direction (including on us), it stopped laughing, and the grin disappeared.
I realized then that the human brain was what was allowing it to experience humor and amusement. Without that, it just wanted to maul things.
Fortunately, I woke up right about then. The alien was staring right at me, no longer finding me funny, but staring at me in a predatory fashion.
