Your Spuffy trivia for the day

Does anyone remember in what episode Spike has the dream in which he realizes he's in love with Buffy? Yes I should know this, and yes I could go looking through episode transcripts for the answer, but I'm lazy. I know it was in the beginning of Season 5 I just don't know when.

I want to know cause I've actually started writing a story idea I've had for some time, that starts during The Replacements (the episode with the two Xanders) and I'm mostly sure that Spike doesn't know he's in love with Buffy yet, but I"m not positive.
