A MacMillan nurse I knew said that a couple of years ago a terminal patient who had already gone into a coma and had 24 hours live - family were at bedside waiting to say goodbye. out of nowhere the lady suddenly sat up, freaking everybody out, and got out of her bed where she went into the kitchen and made a cup of tea. Went back to bed, drank it, and passed away a few hours later. My friend the nurse said if she hadnt seen it she would have never believed it had happened.
