I suspect the story I'm learning for is from Analog in the 1980s or so.
A science fiction writer is woken up from cold sleep, and greeted by government officials who tell him that his stories are remarkably, unnaturally predictive about the actual future, which is why he was revived. Somehow the writer makes contact with a scientist who has invented a device that the writer realizes would allow him to contact his past self - his stories were prophetic because he unconsciously had been remembering details about the real future he woke up in (I think the device was an alien artifact discovered on the moon - and the author had written a story about such an artifact - but hadn't included the bit about allowing contact with a past self). Maybe he was awoken specifically to deal with the alien artifact, because that discovery matched something in one of his stories.
He keeps this a secret from the government so they will continue to think he's a valuable prophet worth subsidizing. At one point, he mildly threatens the main military liaison he's been dealing with, by saying he will write a story in which the liaison's job no longer exists (because the military would no longer exist). At the end of the story, the liaison talks about one particular story he had liked (independent of its prophetic nature) and the writer says that the female villain had been based on his wife - the liaison says "Oh, she seems charming" (or words to that effect) revealing to the shock and horror of the writer that the wife had also been frozen and revived.
