Had a dream I was a shadowboxer in an empty train station

I'm in this cavernous old station, no trains, no people, just me throwing punches at my own shadow on the tiles. Every jab echoes like a drumbeat, and my shadow's not following my moves—it's leading them. I wake up before I land the final hook, but my hands are still tingling. Been thinking about it all day, how even in dreams we're chasing something that's already ahead of us.
