Usually my dreams have a recurring theme of either embarrassement or abandonment, but I have a lot of arcade dreams too.
In the most recent one my friends and I were trying to pick up these huge free cabinets from the mall, but for some reason security was after us. And man were those cabinets huge. One of them was like some Capcom scroller, but it was in a giant blue submarine cabinet (shaped more like a diving bell though). All of them were insane cockpits like that.
I remember another dream where I bought a Q*Bert from down the street, and I was trying to drag it home behind the car with a rope tied to a piece of wood with casters on it.
Does anyone ever actually have good dreams? I really can't remember having a good dream, most of mine would at best be classified as uncomfortable, while most of them are more like nightmares (although what scares me most isn't what scares you most, thus my dreams probably wouldn't be very scary to you).
