In a dream, equal sign represents your relationship. You are equal to the person you love or admire. Additionally, the equal sign can represent equality in bed, because it signifies satisfaction and comfort at the same time. So when you wake up, you feel slightly happier than before you went to sleep. But if you want to be honest with yourself, it could also mean that there’s some unhappy element in your relationship that needs fixing and/or more commitment from one partner to another.
Also, an equal sign in a dream means that you should treat yourself with equal respect and importance as others do. This symbol also signifies sexual equality since both sexes should be treated with equal respect by each other, otherwise the sex imbalance will be a problem in society.
