There is a building, and a child is playing with a ball on a balcony that faces an open courtyard. I am standing somewhere below, in the corner. I am watching that little boy play, and play, until suddenly the ball slips from his hand and he follows it through the stairs. The next moment, he falls and is lying dead on the ground. But right at that moment, a parallel structure becomes visible to me, which is exactly the same as the one I had been seeing. In this structure that overlaps with the current real structure, I can see the boy still playing with his ball.

I just cannot understand what this is, what any of this means, when someone unknown tells me that death is nothing but entering another dimension. He calls it the fourth dimension.
