Hey Guys, I am having goose skin here reading your responses. It feels eerily unnatural, ghostly, mysterious and strange to heard this stuff from you. I wonder what other musicians, songwriters and music enthusiasts saying about this topic. I do believe that other great songs and music we have out there were made from music in dreams, i.e... Mozart, Handel, etc., and even other modern composers. I googled this topic but it seems nothing comes out of search engine.
By the way, the original title of the song "Yesterday" was "Scrambled Egg", and then after many thoughts and a trip to Portugal in 1965, was changed to Yesterday with the lyrics. Here's the song on YouTube. It makes my heart beat fast.
