Dreaming

I had a tornado dream last night. All the Internet research I find says that dreaming of tornadoes means you have some sort of turmoil or volatile situation in your life. However, these theories all seem to be responding more or less to nightmares. Which didn't seem to be the case here. In my dream, an old friend and I were driving around in the car she had in high school (maroon Corolla) through sort of a mountainous and green area. And there were tornadoes developing all around. We were trying to avoid them and thought we needed to stop for cover until they blew over. We pulled up to a gas station type place and asked the attendant if we could use his basement (which seemed to be more of a TV/recreation room). The attendant did not seem to be aware of any tornado, nor did he care. He also had on overalls and a plaid shirt. He declined our request, so we shrugged and just kept going. My friend had to do some maneuvering to avoid the cyclones and we eventually made it back to her house. Where we took off our shoes. We never really seemed frightened at all by the tornadoes. I think I called my mom when I got there (but my mom was different in the dream than real life. Perhaps more of a "mom" especially because I called to tell her I wouldn't be home for dinner and my real life mom would never be making dinner). That was it. No cold sweats, no screaming, no sudden jerking awake. So does the tornado dream theory still hold up if it wasn't a nightmare situation?
