A video essay exploring the many hidden secrets in Paul Thomas Anderson's new Radiohead music video: "Daydreaming." Written, narrated, and edited by Rishi Kaneria (@rishikaneria).

The ideas in this film have been gathered from various online sources and fan theories and synthesized with the author's own personal interpretation and observations.

Talk about many theories! I mean, just the fact of Thom Yorke having broken up from his girlfriend after 23 years together, and his walking through 23 doors in the video... I wonder how many of these theories are intentional.

Thanks to Johan for the tip!
