“As I researched sleep, I found that we sleep in intervals. The REM intervals loop several times a night. Each loop is about 90 minutes long. It is the same running time as an average feature film. So maybe the running time of films fulfills our subconscious needs? Therefore, entering a movie theatre is not unlike entering a dream. Films hypnotise us and take us to new worlds. Sleeping and films are like twin realities.”
