It is said that shadows in our dreams symbolize our fears in life and all that we keep hidden deep inside our consciousness. While our subconscious is often trying to tell us something, it usually takes the form of a dream that we might not understand. The shadow can also represent an unconscious thought within ourselves, as well as a lack of self-awareness of troubles that lie ahead.
Dreaming about shadows signifies the fears, anxieties and other issues that have lingered in your thoughts. You need to relax more, or the person or event you have neglected will continue casting shadows over your carefree life.
