Will Save Vs Dream Dog

I went back to sleep after the cable guys came this morning, and I had a dream. Often I can control my dreams, that’s how I know I’ve got a high Will saving throw (although I was hypnotized once). In my dream, I realized it was a dream and I thought it might be interesting to gather some imperial evidence. To test the resolution of my dream vision I went up to this pickup truck and studied very closely its surface. It was, indeed, very detailed. It looked exactly like a real pickup truck, not just dream-stuff. It had all bubbles and scrapes in its paint job and some sticker on the back with a very professional-looking logo. Then I think there were dogs wandering around the parking lot so I climbed up onto a roof to avoid being attacked. I think I was attacked anyway.
