First I watched Back to the Future, and then I read Nick Hornby's Slam, where the protagonist gets magically flung into his own future by Tony Hawk. So I guess it was inevitable that I had a time travel dream. I turned up back in high school...but one with a much, much better library than it really had.
Someone was trying to find a book, and I said, "Oh, I've got access to some great databases. I mean, not as great as Veronica Mars'..." And they thought Veronica Mars was just some girl I knew, so I didn't explain.
Of course, since it was only a dream, I forgot the crucial detail that my special URLs and passwords weren't going to be good for well over a decade. Oops.
