There's no scientific proof that these after - death visits are real. However, from a psychological perspective, it might be the mind's way of dealing with the loss. Our brains are complex, and when we miss someone deeply, we might have vivid dreams or hallucinations that seem like visits from the deceased. But who knows? There could be something more to it that science just hasn't discovered yet.
From these stories, we can also learn about the human need for hope and closure. When someone experiences an after - death visit, it often gives them a sense of peace and closure. It's as if their loved one is saying goodbye properly or reassuring them. This shows that we as humans have an inherent need to believe that there is something more after death, and these stories can provide that glimmer of hope in times of grief.
A good novel about the death of a loved one was Embracing Grief: Accompanying You Through the Difficult Times of Bereavement. The book was written by Megan Devine, a master's in consulting psychology and author. Through her personal experience of losing her partner, she proposed a set of ways to get out of grief and get back on track. This book wasn't an academic preaching style. Instead, it gave the reader some inspiration and help through personal experiences and thoughts.
I think you could make a scrapbook. Put in pictures, handwritten notes about their tales, and maybe some small mementos. Another way is to set up a dedicated blog or website to document and share their stories with others.
Some people believe they are real. There are many accounts where individuals claim to have had some form of contact with their deceased loved ones. This could be through dreams, for example. In dreams, a person might see their dead relative vividly and have a conversation that feels very real. It could also be a sense of presence, like feeling that the loved one is near even though they can't be seen.
