April is a symbol of rebirth and joy. If your dream is set in this month, it indicates that things have started well and you will soon achieve the things you had been craving for. If your dream is set in April, but the sky is cloudy, and worse, cold and stormy winds are blowing, it indicates that the things you are working on (business, love, etc.), will go wrong in the immediate future; there will be failures, but they wont be permanent.
