Some doubt that the dream is accurate or even occurred due to the fact that it is only known through two levels of telling. More information is available about her dream by clicking here. The video below gives a brief overview of the dream.
To me the intriguing part of the dream is the patience required to have all her children who had died in mortality. Was the patience for her to wait until the end of her life or was it intended to refer to additional patience after death? Being a parent that has had a child die, I can understand the desire to have that child again and it is hoped that the opportunity to raise those children will occur in the Millennium.
