According to Dream Moods, tattoos in dreams represent your individuality or desire, whether pronounced or otherwise, to stand out more. You might secretly wish to be different or more unique than everybody else (this is especially true if you don't actually have any tattoos). Likewise, a tattoo could symbolize anything that's made a lasting impression on you. Or, you could currently be about to make a decision that could have that kind of massive impact on you and your life.

As for what kind of tattoo you dream about getting, a dragon on your wrist could symbolize you're looking for more attention, or to be rewarded for efforts and actions, while an ace of diamonds shows pride in past accomplishments and a desire to share them with your loved ones.
