Can I get this dream to continue? What does it mean?...?

This guy Tom, must represent what you might want in a boyfriend. He seems to be a take charge type guy who has a lot of guy friends and comes from a well-to-do family. Hanging out with a young girl would have to make you conscious of the example you were setting through your actions. Fighting zombies with the boys would have to do with having a common cause in regard to keeping negative, heartless, type people from messing things up in your lives. Getting married has to do with wanting a long term relationship eventually. You must be not perfectly satisfied with your current relationship with your boyfriend, so that your subconscious mind, which creates dreams, is envisioning other possibilities. Details in dreams are not always so important, what often counts the most is the overall theme. Remember to not get so caught up in relationships that you forget to focus on developing your relationship with yourself, and developing your unique talents and abilities. The more one develops oneself the more one will attract someone who is special. Like attracts like. You may have to see if the relationship with your boyfriend can be improved to meet more of what you want. One does have to work at relationships in order to have them work better. You are young, so you don't want to preclude other relationship possiblities that come your way that could be better. Also remember to always try to be a good example in what ever you do in life or in regard to relationships, so as to be a good example to others younger than you, like the younger girl in the dream. Meditate/pray, exercise, and eat healthy, so that you will stay strong spiritually, and be able to attract the right type of relationships in the future. It is extremely hard to get a dream to continue.
