If you kissed someone in a dream, then such dream means that you are looking for love and affection. The kissing is also something we share with those we love, so it could show the lack of love you are suffering from, therefore you at least dream about it, because you get no kisses in your waking life. If it is not pleasurable for you, or your partner kisses somebody else, it means you are afraid of unfaithfulness.
