I can't say I've ever had an RX-8 nightmare, I've only had good dreams. Here are my dreams that I had posted in another thread:

In my first dream I was driving my 8 through the building where I worked. The cubicles were arranged so that there was narrow tight path with near 180 degree turns winding throughout the office. I was driving my car rally style, drifting around the tight bends, flying past office entrances, printers and coffee machines, coworkers with bewildered expressions on their faces. It was awesome.

The second dream I had was driving through an abandoned industrial-looking city sometime late at night. I was being chased by cops and they finally surrounded me in a public storage facility-like area. They confiscated my car and towed it somewhere. So somehow I found out that they moved my car to this warehouse-like building across town. When I got there and went inside, there were all these other cars on dynos, with import models tuning them!! So I see my car, and the girl who is working on my car is a cute girl I know in my church (I know, dirty me). She shows me my AFR graph that she is working on a computer screen. Dam thats hot!!
