I always recomend trying to interpret the dream yourself, because only you kow what is going on inside of your head and in your life, and dreams are a reflection of what is going on. A dream can highlight things that may be subconsciously bothering you, or anything else really, in a symbolic way.
I read into the symbolism of things being big and things being small (as well as one feeling big/small). To be big or see someone as big means you may have an inflated opinion of yourslef or someone, or may be expressing a desire to be more dominant in a situation or relationship. "To dream that someone or something is smaller than usual, represents feelings of insignificance, helplessness and unworthiness. Alternatively, you may be literally trying to "knock" this person down to size. Perhaps it suggests that you or someone in your life has an inflated ego and need to be taught a lesson. To dream that you are small and everyone is normal sized, suggests that you are suffering from low self-esteem and/or a sense of helplessness. Perhaps you are being overlooked."
Try and see if any of this symbolism applies anywhere in your life-friends, family, work, etc. and if there is something that you can do to fix it. Also look at the emotion toward dreams to see if you see the symbolism as good or bad, etc.
