In this wikipedia article (I know, I know) for the Guns N’ Roses song “November Rain”, it is suggested that when the actress is shown in the coffin toward the end of the music video for the song, she has a mirror over her face because she has shot herself. It is further explained that “the families of head trauma victims (who want an open-coffin funeral) often employ mirrors to give the appearance of a full face.”
I had never heard of this funeral-parlor trick, and it seems unlikely that the family of someone with severe head trauma would opt for an open coffin. So I googled it and found only … references to the the Guns N’ Roses video.
Any truth to this? Are mirrors ever employed in this way?
