Similar to OP: When my ex and I were still together, and I lived in Las Vegas, I inexplicably sat up in bed one night, looked at our fan, and had this gripping feeling of being in West Virginia and feeling very very alone. I knew we wouldn't be together anymore, which seemed strange to me at the time because we were especially close at that point, I otherwise couldn't imagine being without him, assumed we were going to get married, and frankly the thought of this fucking terrified me and I chalked it up to a nightmare. I also didn't think at that point about moving back to WV.
Except that about two years later we broke up and I went to WV, so we weren't together anymore, and about a year after that I was in my apartment alone one night feeling VERY horribly depressed and lonely in my bedroom in the dark looking at my fan, and I remembered that night. It came true. Unbelievable.
But USUALLY the way common way I use my Ne is to make symbolic connections in literature between different ideas, or I suddenly come up with something either relevant or funny that seems categorically unrelated to what I'm writing or I'm discussing with someone, yet it somehow fits perfectly and ends up being extremely clever or at least funny. I also used to write major papers over the course of a semester, not by methodically working on them, but by collecting random stuff and not realizing I was doing it, until I actually sat down to write the paper at almost the last minute and was relieved to find that I had virtually everything I needed at my fingertips.
