I don't know if going in he had a preconceived notion that he would meet the Virgin Mary (a lot of Catholics take that as a given they will be with her in Heaven) but he didn't seem to expect what came during the NDE.
He saw her and it was through her intercession that he was spared and sent back to be more of what a priest should be, teaching morals and dogma, not particularly popular subjects but what priests are ordained for. He had despaired because he WAS going to hell until the Virgin Mary appeared and interceded for him.
Still and all, I can't fit all these into neat categories with no exceptions or overlapping.
One particular thing does bother me. I have a general preconceived notion of the splendor of Heaven but St. Paul says the earthly mind cannot imagine what God has prepared for those who loved them. Also some of the subjects claim to have been caught up into the third heaven, and St. Paul said it was not lawful to tell what he saw and experienced other than that it happened and was obviously a transforming or validating experience.
Well!
Aren't we ALL???
