I have a memory of a poem that has a line something like "coming upon a familiar place, and seeing as if for the first time." Can anybody help me figure out where that idea is from?

We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.

T.S. Eliot -- "Little Gidding" (the last of his Four Quartets)



Wonderful, isn't it? A lot of people who don't remember ever reading a bit of T.S. Eliot are haunted (in a good way!) by those four lines.
