I'm trying to identify a book I read back in 2007. It was a collection of short science fiction/alien stories. From my memory, here is one story that I remember:
A group of astronauts landed on a planet that seemed the same as Earth. The travelers were confused, thinking they somehow landed on Earth again, except it was slightly different; one of the travelers' grandmothers was alive, even though she had already passed. While sleeping, one of the travelers thought to himself: "What if we landed on a different planet... and these aliens mimicked our Earth because they could read our minds... which means they could read my mind right now?" He was right.
What was the name of this book?
