Lyric discussion by Tsuppi 

Thom's repetition of the lines, the almost painful and relentless beat behind it, the subject matter and feeling of absolute panic...

This is a song about trauma. Made beautiful by the absolute genius of Thom Yorke and Radiohead's songwriting and musicianship, both of are truly worth a nosebleed or two, they're that good.

Both of which* -- go me!
