Lyric discussion by ultramouse 

quote from peter fonda: "I said to George Harrison, 'I know what it's like to be dead' And John Lennon said to me, 'who put all that sh** in your head-- You know you're making me feel like I've never been born.' I said when I was a boy, I shot myself. It was an accident, and I died on the operating table and I suffered from a massive loss of blood, and I my heart stopped. So I died three times on the operating table."

Lennon's acid-mind at the time most likely associated that with the Tibetan book of the dead stuff that he was reading/putting into lyrics like Tomorrow Never Knows. Interesting stuff.
