Paul McCartney wrote “Let It Be”. It was inspired by his mother, Mary, who died when he was 14. Many people thought “Mother Mary” was a biblical reference when they heard it. According to McCartney, this is a very positive song, owing to its inspiration. One night when he was paranoid and anxious, he had a dream where he saw his mother, who had been dead for ten years or so – she came to him in his time of trouble, speaking words of wisdom that brought him much peace when he needed it. It was this sweet dream that got him to begin writing the song.
