Hi Chris,
Sorry to hear you’ve lost your parents, but yes, loved ones who cross over do watch over us, and they do reunite with their loved ones who passed before them. They also often send signs to let us know they’re still with us. For example, my husband, who died several years ago, still turns on our bedroom light from time to time. Other possible signs are birds and butterflies that stand out, smells that remind us of them, etc. I’ve Written an article they explains exactly what happens when you cross over, if you’d like more details.
Souls plan their lives before they come to Earth and often choose who their parents will be. They usually work in groups and are often together in various roles through several lifetimes. Each time souls come to Earth, they plan their lives so they can learn and experience certain things that bring them closer to God. Once they’ve learned enough to understand and commune with God, there’s no need to reincarnate. If you’d like more information on this process, I’ve written more extensively on life plans, also.
Hope that helps.
Wishing you well,
Jodie
