Sometimes your loved one comes back to give you a message. It could be that there is after life. It could be information that they did not have an opportunity to share before passing. Perhaps something you need to know about an event in the present time. If they have gone through life review they will often show themselves as they were during their prime in their 30’s. This is to let you know they are fine but also they have settled into the afterlife and all is well.
We call this a VISITATION, not a dream. The spirit has actually come into your dream to communicate with you. If a loved one or friend shows up in your dreams, it is not a dream. They have come to VISIT. It is common in the first few weeks of a passing for visitation of the family and/or friends. The spirit hovers around the family to check in on them as they try to comfort us during the initial period of loss. Depending on the individuals grief they can hang around for a few years. This is why it is important to send prayers to encourage the soul to continue on with the next step of life review.
I am only scratching the surface of this topic in hope it brings more understanding. In love and light
