This song is about dissociation. Thom is on "automatic pilot", performing, doing what he has to do but he is distancing himself from it all. In his head, he's anywhere he chooses to be, "walking through walls", "floating down the Liffey". etc. He goes from place to place, (probably flying internationally and traveling with the band, going from one place to another on tour), and 'in a little while, i'll be gone, the moment's already past, yeah, it's gone." "Strobe lights and blown speakers, refers to the set-up, sound stagings and light shows that accompany Radiohead performances. "Fireworks and hurricanes", refers to the crowds, fans and excitement in the huge venues they play around the world. "I'm not here, this isn't happening" expresses his dissociation from it all. It feels like a dream...Even he can't quite believe it's real and sometimes wishes he could "disappear completely"...
