Tornado/storm is one of my most frequent recurring dream themes, had them since I was in my teens. The most common flow of the dream is (1) I can see a funnel cloud, but it looks like it's not going to come our way (2) It starts coming our way! (3) Sometimes I (or "we") can find way to the basement; or, I can't seek shelter and I know it's gonna get me/I'm a goner (4) Storm rolls through, sometimes there is structural damage, but I'm unscathed. (5) many times, in aftermath, it's clear and sunny.If I have vivid dreams they always seem to be tornado dreams. No one ever dies or gets hurt in them, but the tornado always just destroys the neighborhood. Don’t ever wake up sweating from them or anything like that. They are just super vivid and intense.
In real life, I've had only one or two close-calls with a tornado situation, so my dreaming isn't based on past event/experience (although living in/near Midwest of course the possibility is always there).
