A heart in a dream represents emotional wisdom. A dream about a heart can be a message that you need to pay more attention to the feelings of someone important in your life. You may have been paying attention to the words that they have been saying to you, but you have not been trying to understand the feelings behind those words.
A heart dream can also reflect a need for others to understand how you feel.
The heart also represents love and compassion.
A metaphorical “broken heart” in real life can be symbolized by a heart that is physically damaged in a dream. If your heart is injured in a dream, this may also mean that you believe that nobody understands your feelings.
