Is it true that people suffering from some heart diseases and/or near
death gets bad dreams?

I have some first hand info. Of late I am suffering from problem with
irregular hear beats. I started feeling pain on back of my shoulder and
sometimes at chest. Get tired easily and find difficulty in breathing.
Then I started getting bad and frightening dreams. Usually I was a
silent sleeper always, never got up with bad dreams. But now that I
found problem with my heart I started getting bad dreams. I found one
pattern common in all my dreams in last three months. Objects I see in
my dream are those which I fear the most. I see lizards crawling over
me, snakes catching my legs and short ugly men jumping over me from
cup-boards... I have been thinking whether these dreams are good for me
or bad to my heart.? Will it lead to heart attack? and Why is it that I
see these sort of frightening dreams now?? I realised one thing. This
is the brain game. Its good for my heart. I think brain deliberately
does this. For the heart patients sometimes while they are sleeping,
heart-beat rate might tend to go abnormally low and cause death while
sleeping. At that times, brain plays the trick. It makes you dream of
the objects of which you get fear. And the fear factor will make your
heart beat faster and get to normal Rhythm,.
For an adult like me it was difficult for my brain to create the dream
of which I fear. I won't get feared watching dream of cockroach
crawling on my leg. A small child might get feared with such dream, but
not me. So I realised that in last three months, my brain tried all
sort of objects off which I use to get feared in the past. Also
arranged the dreams in such a way that normal adult get feared. Like
jumping off unusually short and ugly man from a cup-board. Any normal
person will panic with such thing and heart rate will increase.

So I believe its a brain game and good for heart patient.
