I generally don't remember my dreams unless I wake up immediately after having them, which means the dreams I remember are either (1.) nightmares that woke me up, or (2.) dreams I had in that half-asleep state (what's it called again?) before waking up.
I was in my car, driving south on I-494 in Plymouth, MN, (a western suburb of Minneapolis), with some very ominous-looking storm clouds in the west. It was daytime (probably afternoon or early evening), but the freeway was almost empty of traffic. I switched between the middle lane and the right lane pretty freely. I ended up going east on I-394 into Minneapolis.
In Minneapolis, I got off into an industrial neighborhood just southwest of the I-94/I-394 interchange, just west of downtown -- except the neighborhood was much bigger than in real life, and it was on both sides of the street I'd exited onto (unlike the real-life major street in that area, Dunwoody Blvd., which has the Parade (a park) and the Sculpture Garden on its south side). I had my windows open, and I heard the tornado sirens turn on.
I drove around a bit, looking for a good place to seek shelter, and and wondered aloud with a few other people about where to go. I pulled into a gravel lot next to a small brick industrial building. Someone said there was shelter a few blocks away at 16th and [some street]; we were at 16th and [some other street] (no relation to any real-life streets). I got onto another street nearby and headed north a bit, where I accidentally cut off a black guy in a junky car who was pulling onto the street from the opposite side. We both headed north toward the freeway; I almost went north on I-94, but changed my mind and moved left to go west on 394. The other guy got onto northbound 94 (whose dream-fictional ramp was also signed as I-694). Unfortunately, I didn't want to go that way -- I wanted to get to 16th and [that other street]!
Then I woke up enough to think "That was stupid," and wanted to back up the dream to that gravel lot, but I was too awake to continue the dream (doh). After ruminating on the dream for a few minutes, I found a pencil and paper and took notes on the dream so I wouldn't forget it.
I love how dreams like these have lots of nonsensical details, but at the same time, the logical part of my brain is very annoyed by them.
