I will always remember having a dream where my mom came back, hugged me in my dream and that hug felt like her saying she understood why I treated her as I did and that she knew I loved her and she loved me (that's a lot of meaning from one hug--isn't it?). I had not been at peace about my mom's death for years and I was after that dream. Perhaps that was just me processing what had occurred. On the other hand, I have seen some on the internet say that most people "sleep" (Enoch is one of the exceptions to this they say) until the resurrection and if you are visited by the dead it is demons masquerading as something good but their intentions are anything but....
