Polish Wikipedia has a very substantial article on the U.S. state of Alabama. Can you imagine a Polish encyclopedia pre-Wikipedia caring this much about Alabama?
There are those dreams that sort of stay with you, lingeringly, coming back in bits and pieces over the first few waking moments, and then only as feelings and familiarities later. As the years go by, you remember, again, in the moments where the same thing happens again, and you cannot place whether the memories are real or imagined. But you know you've lived this before. You feel like you know it implicitly.
