Giving or receiving affection in a dream usually represents a desire to give or receive affection in waking life.
Dreaming that you are being affectionate towards someone can be a way of caring for a part of yourself that has been neglected.
Think about the qualities of the person that you are showing affection for. Are these qualities that you have failed to develop in yourself?
If someone is being affectionate toward you in your dream, think about how you feel about the affection that you receive? Do you welcome it, or does it make you uncomfortable?
Receiving unwelcome affection in a dream can mean that you feel that someone does not understand you or that someone is trying to manipulate you.
