It means a bad event,bad luck at the specific period,a threat or a danger!8 years ago,I dreamed that 4 tornados,surrounded my country!Well,I can say that things were not so good then and on.

Occasionally, I have tornado dreams, though they differ in degree of threat. For me, they are certainly stress and fear related, but I think the tearing down and rebuilding factor is just as significant. Sometimes I am in a fortified space, like a brick building, and sense a bit of control over the path of the tornado. Other times, I'm caught out in the open, searching for an overpass to use as shelter. Often, when I am really really stressed, the funnels come at me in sets of three or five, as a whirling formation. The upside is that I always find a safe place, and survive unscathed. So far, anyway.
