Dream Of Rushing Water And Cement Truck

Last night I had one of those unusual moments that really doesn't make sense.  It was a dream about rushing water and a cement truck.  In the dream, the location was in a mountainous and hilly location which had gotten a lot of sudden rain.  For some time the weather forecasters had been telling people to take cover because there was going to be enormous amounts of rain fall.  However, people went along with their daily lives thinking that all of these warnings meant nothing.

Then, it happened!  The rain started to fall suddenly and in a great quantity.  It came rushing down out of the mountains and hills towards a valley and soon the water was so deep.  My friends and I along with some people I really didn't know, were driving this cement truck and drove it on to a big raft.  We got there just in time for the water to swoop down and lift us off with people trying to jump on the raft as the water pushed it away.  People were running and screaming for help, wanting us to stop to let them on the raft, but there was no way to stop the raft.  Finally the raft came to a standstill as the water began to spread out.  I don't exactly remember what the cement was for, but I believe it was to start building the wall of a dam up.
