I had a dream that Sara told me about a dream that she had where she lived in a different town (the name of the town reminded me of Elkhorn, but it was different and it was northwest of Madison and on the north shore of a big lake) with a different boyfriend and I was like "oh yeah that's a parallel universe and it's real" and then I went to visit it. The Sara in that universe didn't know me, but recognized me sort of subconsciously, like how the characters in Eddie keep doing when they run into each other for the first time again and again.
Then there were other parallel universes, including one where we were climbing around the inside of a silo or a warehouse full of straw bales, and there was a bird or a cat or some other creature that we were helping, and maybe they were also helping us by showing us where it was safe to step.
