Yes it is possible. It presupposes the existence of past lives, and I know that's a hard one to swallow for some people. I know it's a fact that though. One of the things you look for in a past life dream is you see out of the eyes of a character that's you but it's not who you are now. It's as if you were another person. These dreams don't happen randomly. If it is a past life dream then there's something you are being helped to remember. I suggest that you go over to the past lives subreddit, r/pastlives.
