My Mom’s aunt(Her husband) was in his 80s, this was many years ago, he had previous heart attacks in the past, but one day he went to go take a nap and a few minutes later heard a large crash, his body fell off the bed, he was dead, had a massive heart attack. Not sure if that this occurs in all cases I guess it depends where the person was on the bed to begin with(Edge of the bed, etc) but if a person is on the edge of the bed and has a heart attack I think the body would fall off the bed
And to have his hands folded on his chest like he was laid out in a casket.
I find this so hard to believe but I have never been around someone who has actually had a heart attack..just what I see in movies. It just seems that a massive heart attack is going to cause the body to move.
