People tend to “see” former friends and family that have passed on right before they die themselves. I don’t see any reason why she couldn’t have mentioned her late husband, went back to sleep and then died later without ever saying anything else.
Who was, and why was anyone in her room that night to even hear her? They said she died peacefully in her sleep, which means she died, and they found her that way the next morning. They said she was in "good health" beforehand, but perhaps she wasn't, and required someone to be in the room with her 24 hours a day. Why they can't admit anything, and decide to tell "dueling" tales about her last moments is beyond me.
