As a symbol, Deer represents longevity, swiftness. Deer also is a divine messenger.

In shamanic tradition, deer stands for gentleness. When deer appears to you, "you are being asked to find the gentleness of spirit that heals all wounds. Stop pushing so hard to get others to change and love them as they are. Apply gentleness to your present situation and become like the summer breeze: warm and caring. This is your tool for solving the present dilemma you are facing. If you use it, you will connect with Sacred Mountain, your centering place of serenity, and Great Spirit will guide you."
