Deer represent grace and spirituality. Deers are important dream messengers, so pay attention to where they lead you in dreams.
Some specific dream meanings involving deer: To see a deer in its natural habitat foretells a new and pleasant friendship.
If the deer was captive or in unnatural surroundings, this symbolizes emotional upsets and/or disappointment in a trusted friend.
To see a dead or dying deer, or to kill a deer in your dream, is a warning to look out for a backstabber who is masquerading as your friend.
