The meaning of days in dreams is a reference to one’s mental state. Sunny days can mean happiness or it may refer to someone’s work life and their general outlook on what they are doing or if they are becoming enlightened. Some people who have pleasant days assume that it means fortune but in a dream state this typically doesn’t represent fortune at all because the person is possibly looking for outside validation for the internal improvement that is taking place resulting from their shift in attitude.
People always dream of pleasant moments in the day like when they spend time with their loved ones or do something they love.
