I have watched your posts since 1998 and would never doubt your sanity or integrity. (almost never, since I have recently seen what illness can do temporarily to the mind).
But I have also seen something that wasn't there, just as clearly and solidly as anything I have ever seen. I was also in a position to understand why I "wanted" to see it, and have had since college, a theory of mind that accepts such phenomena as part of the normal working of the mind. I also have vivid dreams, which I often remember in detail for several minutes after I wake up. Some of these dreams have all the texture of reality. I have even made jokes and puns in dreams that I can remember when I wake up. (I have written a few down, but they don't look so wonderful later in the day). So I am never shocked at what sane people experience. I am sometimes skeptical of their interpretation of what they experience.
I'm afraid that to break through my skepticism, I would have to experience something with a bit more substance than a personal vision. I don't know what form that might take. Predicting the future? Interesting, but we all make predictions and some of them come true. My favorite example, which I am unable to locate via google, is the CD cover by the group Coop, showing the wtc towers burning exactly as they did, but printed a month or more before the event.
For instance, the Bible records many prophecies and their fulfillment. Much of it is confirmed by other archeological evidence and historical documents.
As I recall, one of the tests of a Jewish prophet was that he had to be 100% accurate all the time. Therefore, the prophecies had a present day fulfillment during the prophet's life and a future fulfillment.
Also, the many prophecies of Christ appearing as the suffering lamb are fulfilled. The prophecies of His returning as the conquering lion will be next.
There are also promises in the Word which are fulfilled personally (I've experienced many of these!)
