My DD is a nurse and has worked in hospices.
She tells me that when a person has died the nurses take great care to wash their body and dress them before they leave the care of the hospice.
The last thing the nurse does before leaving the the room is to open a window so that the spirit can soar free.
This practice is common among nurses whether they work in a hospice or not.
When your window is opened Zombie don't look back. Your family and friends will be in tears but you will be free of pain and cancer. Fly out of that window and soar upwards to where the angels are waiting.
