Umbrella – The umbrella is used to keep rain and other liquid off of you. If you are going to the movies, go and see Rocky Horror Picture Show and you will understand. If you dream about it actually raining cats and dogs it means that you have a wonderful and original imagination, you should be in a field that requires the right side of your brain. If you dream that you are walking in the rain without an umbrella it means that you are not prepared for what life is about to hand you.
