Shaking hands with someone in a dream means signing an agreement, receiving benefits, a pledge of allegiance, honoring one’s promise, making a commitment, good intention, signing a contract, or cherishing a friendship.

Gives gender-specific: If the sleeves of the two hands are masculine and feminine in the dream, or the hands are bound by cords, the handshake may symbolize matrimony, the latter by pagan rites. You might like to consult the entries for bonds, cord, gloves and wedding / wedding dress / wedding ring for further information.

Interpretation 3 — Versatile - Anonymous

Material aspects: Agreements are often sealed by a handshake, the idea being that we are not going to attack our opposite number if we have shaken hands. In dreams, shaking hands will represent at least a partial bond with the other person since, from the times of chivalry, we remove our gloves in order to do so.
