mccartney said he woke feeling blessed by the visit. he went to the piano and put the dream into a song. “mother mary comes to me” refers to his mother. mary was her name.
it was so wonderful for me and she was very reassuring. in the dream she said, "it’ll be all right." i’m not sure if she used the words "let it be" but that was the gist.
mccartney does not claim that he remembers every word. he is clear about the visit and the feeling, but careful about the exact phrase. that stated uncertainty is part of the primary record.
the song became the title track of the band’s last released album. the dream also belongs to a familiar type: people in grief often report vivid dreams of someone who died and describe them as deeply consoling. whatever the cause, mccartney carried the reassurance into waking life and gave it a lasting form.
