One night in 1967, the phrase "words are flowing out like endless rain into a paper cup" came to Lennon after hearing his then-wife Cynthia, according to Lennon, "going on and on about something". Later, after "she'd gone to sleep – and I kept hearing these words over and over, flowing like an endless stream", Lennon went downstairs and turned it into a song. He began to write the rest of the lyrics and when he was done, he went to bed and forgot about them. "I was lying next to my first wife in bed, you know, and I was irritated, and I was thinking. She must have been going on and on about something and she'd gone to sleep and I kept hearing these words over and over, flowing like an endless stream. I went downstairs and it turned into a sort of cosmic song rather than an irritated song, rather than a "Why are you always mouthing off at me?" [The words] were purely inspirational and were given to me as boom! I don't own it you know; it came through like that."
