I had a dream that there was cannon trucks driving up and down the streets and this military guy help me and my fam and told us to go outside there was snow in only our yard so I looked up the meaning of a cannon in ur dream and this is what it said. To dream of a cannon represents drastic measures or choices. Finally deciding to take action in a big way. Feeling that enough is enough. Being unwilling to put up with a problem ever again Guys be prepared war is coming God says it.
