Topics: What does it mean when someone says "You're breathtaking"?
We often have our crush at the back of our mind and this deep inner desire to be with them can actually cause us to dream about the person.
Dreams will often reflect our emotions, concerns, preoccupations and things taking place in our waking life, so the more you think about something or someone, the more likely you will be to dream about them!
When you dream about your crush it therefore reflects your actual attraction, fascination or infatuation towards this person. To see an old crush in a dream is a reflection of your feelings during that stage of your life.
