Two last night that I managed to retain.
In the first, it was revealed that WWII had only been won by the allies due to Time Travel. They were so short of manpower that they had to send back draftees from the present day, who were on pain of death not to breathe a word. I was sent back with them and was lumped in with a bunch of British soldiers, including one who'd been sent back in a weird multicycle, so he was young enough to be trying to teach business and confidence to his younger self who was a bar rat in his parents bar where we all hung around waiting for D-Day. Eventually those of us who'd been sent back via time travel were able to identify one another and silently winked or nodded to acknowledge this.
After a while, the war was won though it took a little longer and was a little harder than I'd remembered and while I sort of minded missing out on the future I could live with that. The main reward I was looking forward to in my old age was to live long enough to get back to my mp3 collection. Eventually, as we got closer to the present day, around the 80's, there were more and more reports of strange attacks on the North American shores. These had actually been very sporadic in the 60's and 70's and were mostly disregarded as odd individual incidents, but now became too frequent to ignore.
That's when they revealed that we'd actually lost the war in Europe and had been fighting a long defeat since then - presumably because of german counter-time-travellers, copying us - but that the western governments had hidden this to avoid inciting the hidden time travellers in their midst. Now the war had come to us.
In the second dream, there was a huge fuss, because someone had discovered that Eli Wallach was actually the oldest person in history - by a crazy margin. According to newly revealed birth documents, he'd actually been born around 1856. People wanted to research this astounding feat and figure out what had happened, but it actually turned out that I had killed him and replaced him myself as a very young man in the 1920s, after luring him to a dinner party that was a trap.
