I wouldn't make visions doctrine.
My desire to explore history is a strong thing even if it's horrible. I highly doubt I can explore grave yards, old battle sights, navy bases in heaven.
I would be remiss if I didn't add something negative. Not that I want to put out the fire of future bliss, but part of me is laser-focused on truth, reckless or not. Behind it all, though, is the powerful motive of my love for God's word, which if compromised will lose its zest.
One of my 1st great attractions to visions of the future came from Dr. Eby. Everything he said sounded so "God-like" and "possible," and all that. But then he predicted that Christ would come before he died, which didn't happen. Does that throw all of his visions into the sewer? I don't know! He did crack his skull open!
Anway, I don't look at visions at "doctrinal" or authoritative--they are just given for us to consider, whether real or symbolic. Personally, the source of my authority comes from explicit statements made in the Scriptures. They are my "rule." Anything beyond this has to be looked at as "maybe" or "not."
A number of "prophets" I really respect have had elements in their prophecies that seem to reflect human flaws. I know that it's said prophets are to be viewed as genuine only if their prophecies are true. But I think that requirement is not indicative that the prophets themselves must be sinless.
I do think some of the modern "prophets" see visions more than precise prophecies, and so are interpreting the visions for themselves, and perhaps even adding to them an imperfect impression. I cannot deny the unbelievable precision of some of their prophecies even while, at the same time, missing the mark in some ways. But I remain open on this...
As a personal note, I attended Melodyland Christian Center for a few years in Anaheim, CA in the 70s. Pastor Ralph Wilkerson, at that time, wrote the book "Beyond and Back," which was used as source for a movie made with the same name. Wilkerson later said that the movie changed things improperly. They were accounts of those who died and saw things before being rececoverd.
If our memories are completely healed we may be able to look into history without all of the agony those goes along with the negativities. If some of these visions mentioned above are true, then you'll probably have lots of lengthy books or DVDs that look into the past with technical precision--nearly real! ;) I don't think I could stomach it personally, even though I like history, as well.
