Kissing someone in a dream is a symbol of respect and acceptance. If you kiss someone in a dream, it is a sign that you are beginning to accept that person or something that person represents – an idea, a situation, or even an aspect of yourself.
If you dream that you are kissing someone that you do not like, it can mean that you have to accept that you have qualities that you do not like when they are exhibited by other people.
You need to understand why you do not like those qualities, and then decide whether you should learn to accept them in yourself or whether you should try to change.
Kissing in a dream can represent making an agreement with someone else, or with yourself. It can be a sign that you have come to an understanding about something.
A dream that you are kissed on the forehead can mean that you feel blessed in some way.
