Ever made a movie?
If I made a movie on a Biblical event, I would expect to have some poetic license just to fill in gaps, but when I find out, and read the book for myself, and see that those gaps came from the writings of someone who believed that angels took her back in time to the original birth of Jesus, flew her around in the air and kept her up there for a while...I'd either call that insanity or demonic posession.
