Deer symbolizes grace, beauty, and gentleness. They are very agile and fast runners allowing them to escape from predators. They are also highly adaptable, and their hooves allow them to quickly navigate rough wooded terrain. Deer are social creatures and depend on the herd for safey in numbers. Each group member watches over all the others.
When deer appears to you it reminds you to be gentle with yourself, to appreciate the beauty that surrounds you. Deer reminds you that even in challenging times you have what you need to survive and thrive. Deer sometimes appears in challenging times to tell you to "gather up" with your friends/family and work together in the spirit of cooperation.
Deer in its natural habitat in a dream symbolizes new friendship and fellowship with others. If you kill a deer in a dream it symbolizes a friend who will turn on you.
