The Diodora's one was a nightmare and its purpose was to lead Issei to accept his feeling for Asia, it was a plot device. Chichigami said clearly that he made that vision, and he also made him see oppai that Issei will conquer but that he has never seen yet, so it's obvious that Chichigami sees the future or at least part of it.
