I had a dream and I want its interpretation please?

a day in a hallway at college, I was wearing: a dark blue suit, a light blue shirt with a tie, long and thick of a strong and striking orange color with something like small designs like blue ovals or clouds and scratches, I first saw me dressed like from the outside, then from myself, I hold the tie and detailed it closely, then I looked forward and saw my cousin-brother, wearing pants and jacket of strong blac k color, I do not remember very well the color of his shirt, but he wore no tie. Many people passing by us and being among us during the dream. This dream was very real, deep and intense, a detail to note is that my cousin-brother teaches at that university.
