a couple nights ago i dreamed i was with friends at a store and i turned to call to my other friend we called country she had her hood up, i kept calling her and she turned around for a split second and smiled she had a deep blue hooded sweater and long dark brown hair, she then turned back and kept walking and i just shrugged it off and shuffled through things on a shelf when i came across a missing persons sign and her face was on it i looked for her but couldn't find her after that.
Oh, I'm sorry. I misunderstood you. I thought the friends in your dream were people you knew in waking life. I think this other friend in your dream represents a part of yourself that is hidden inside you and you didn't know existed till now. Maybe if you have more dreams about her you will learn more.
