What's scary is I have similar dreams, most occur after the disaster. Massive flooding near worldwide but there are survivors and the water(s) starts to recede(after the damage was done).
I don't have any 'beginnings' of these flooding dreams...unless.... I also have alot of dreams of Earthquakes and tornadoes but these always stop early into the disaster so I don't know these two 'types' of recurring dreams are related.
Wow, that Is crazy. I have a reoccuring dream where Im standing on a beach looking at this wall of water coming at me. I just stand there, kind of in awe at the shear size of the wave coming.
