The belief or not in reincarnation is wide and varied, some dismiss it completely, others would like to think there is something more, there are those who believe without question and those who are able to regale you with explicit details of their past life exploits. Some have near death experiences, they leave their bodies for a time then return to tell the tale, their perceptions then altered for the rest of their lives. Usually at the moment of rebirth the personal memories disappear so that that memories, thoughts and feelings are not transferred from one life to another.
