WG, I think that's a good possibility. It's not uncommon for dying people to mention that a dead mom or husband was there, etc. A mother wrote on a forum for grieving pet owners that her little girl was dying of leukemia and suddenly sat up in bed, her face brightened and she cried out, "Fluffy!" (the name of her cat who had died) and then fell back and passed away with a smile on her face. Science might tell us that these are hallucinations, but I believe that spirits live on and may indeed escort dying loved ones to "the other side."
