As he came back to his body at his desk, he realized he had a sheet of vellum like substance in his hands with the 120 predicted events/situations/items written on it in a beautiful hand written script.
He was quite tired so he just laid it down on his desk and went up to bed for the night. The next morning, the vellum like sheet had started to disintegrate. He scooped the pieces into an envelope and showed them to a number of people over a week or so, by which time they had 'evaporated' away.
Normally, I think dreams and visions are likely to be primarily for the person having them. But in these end times, I believe they will be increasingly for the Body of Christ and for the world, even.
