Three has to do with commitment to the subject matter of the dream. It stands for mind, body and soul and is a request to commit mind body and soul to improving yourself in the direction indicated in the dream. Three will often appear in dreams about the heart as people who have suppressed their feelings often lack passion and commitment for new things in life. It is also similar to a broken 8 in appearance and 8 always symbolizes the heart. A triangle or pyramid also indicate commitment and request the dreamer to meditate on the subject matter of the dream.
