Environment - Non Weather Related; Procedure
Upon touchdown and landing with flaps 25; The nose aggressively pitched up when the spoilers deployed. The pitch attitude appeared higher than normal and increasing. I could not discern if we had become airborne again. The landing was normal; calm winds; landing behind a Boeing 767. At this point my First Officer stated...'watch your pitch'. I elected to go around. We carried out the procedure and were vectored back around to land.Suspect a flaps 25 landing/ spoiler deployment combined with possible wake from preceding 767. Flaps 30 landing to help prevent a higher pitch attitude upon landing.
B757 Captain reported experiencing a pitch-up after landing that led to a go-around.
