IF there is any substance from this dream, (can't be explained by watching a movie or another source), and you feel it means something, then look at weather disturbances as being symbols for our inner turmoil here on this earth.
The vehicles are our consciousness.......(how we get around in life)
The weather is condusive to being our emotions (generally speaking)
A hurricane , a tornado, is being caught up in emotional storms (conceivably)
If there is water, that's an easier one, because Lakes, Rivers and slower moving water, more placid emotions......
whereas, Oceans , Squalls, torrents of rains, all of these are indicative of "strong" almost out of control emotions........possibly.
The ocean waves for instance, "come in and they go out"........
changing emotions, OR
When the waves are "crashing onto us or the shores", this then is simply our own emotions, being "likewise".
Dreams are fascinating, the more you post them, the more of a "pattern" will begin to come through for you.
