This didn't happen to me, but to my mum and nan.
When my great grandfather died (we called him Bluey because of his red hair, as you do) my Mum was in the bathroom getting ready for work. She said that she felt someone touch her arm and then whisper "take care of your Mum for me" just before the phone rang telling her that he passed away in his sleep.
Fifteen years later my Nan had a similar experience when my great grandmother died. She was also in the bathroom and she looked into the mirror and saw her mother standing behind her. She told her to "Look after those girls" referring to my mum and Aunt.
Probably sounds silly but it is nice to think that they are still watching over us
