I haven't given it much thought yet, but right now, my vote is going to go to the USS Brattain, from TNG's Night Terrors.
Thirty-something people aboard all go completely insane from REM sleep deprivation, and murder each other, in all manner of gruesome ways, over a period of weeks adrift, where they fell into mutiny, psychotic episodes, & rampant paranoia. Honestly, that captain's log is just plain terrifying
