Life is continuous (there is only death of the body) so it's not possible to RE-incarnate. BUT, as spirits I believe we do have human embodiment as many times as it takes to learn the lessons needed to advance spiritually. We all have the same lessons to learn and we will all learn them, at our own pace. We agree before we are born that we will take on a certain lifetime in order to learn a particular "lesson". Yes, I believe I've been born many times. We are all spirits having human experiences in order to advance.
