Heres a passage from a dream webpage.
To dream of a kiss, denotes love, affection, tranquility, harmony, and contentment. To see others kissing in your dream, suggests that you are too involved in their personal lives and relationship. You need to give them some space. If the dream ends just about you are about to kiss someone, indicates that you are unsure of how he or she really feels about you. You are looking for some sort of relationship with this person but you are not sure about how to go about achieving it. If you are heterosexual and you dream that you are kissing someone of the same sex, then it represents self-acceptance. You are acknowledging the feminine or masculine side.
To dream that you are kissing someone's hand, signifies respect.
To dream that you are kissing someone else's boyfriend or girlfriend, indicates your wish to be in a relationship and to experience the energy of love. You may be sexually acting out and desire to awaken your passion. Alternatively, it indicates a lack of integrity on your part.
If you are kissing a close friend, then it represents your respect and adoration for your friend. You are seeking some intimate closeness that is lacking in some waking relationship. It may or may not signify a romantic interest for him or her.
To dream of kissing an enemy, signifies betrayal, hostility, or reconciliation with an angry friend. Consider also the saying "this kiss of death". If you are kissed by a stranger, then your dream is one of self-discovery. You need to get more acquainted with some aspect of yourself.
