 All the souls that we've been with, whether it's dog, father, mother, sister, brother, aunt, uncle, the ones that have made the most impact and the ones that are in our core family usually will wait for us all to cross over. And then we all reincarnate together. Now, the relationships can be completely different. Your dog may be your husband in the next life. I truly believe that a soul will reincarnate at least once in its eternity.
