#1 I had a dream of seeing a huge burst of a fire ball coming towards a few people dressed in white tunics.

#2 I had a dream I'm at the shore( beach) and a huge wave covers me an all the land and sand around me.

#3 I had a dream I walked outside and all the buildings  everywhere, as far as you could see were demolished, rubble was everywhere.  No buildings were left standing. 

#4 I had a dream I had to hold onto the gate outside my home, a large gush of water was flowing down the streets, down the side walks pulling everything in its path.
