No one is too old to be comforted after a nightmare like that.
Very seldom I will have those kinds of nightmares where I actually wake myself up trying to yell or scream, but the worst one I remember was this:
I was watching a plane in the sky. It was doing loopy loops, the clouds were beautiful. It was a very peaceful scene. Then I watched as the plane headed straight for the ground and exploded. In my dream, both my brothers were on the plane.
I genuinely cried for a while when I woke up from that one...it was so real, and so horrible.
