Palm of hand
The open inner side of the hand — the surface of giving, holding, and receiving.
A palm of the hand in a dream is the dream's image of the surface that gives, holds, and receives. The palm is the unarmed side; the fist is the back. The dream brings the palm when something in your life — an offer, a request, a piece of honesty about what you are holding — is being conducted through the open inner hand rather than through the closed one. A palm held out open in greeting is the dream affirming the offered vulnerability. A palm held out and slapped away is the dream noting that the offer was made and was, by the other party, refused at the gesture itself.
