My Platonic Sweetheart is a short dream narrative that was originally titled "The Lost Sweetheart" and written during 1898. It was published posthumously and is believed to be based on a recurring dream that Twain had for most of his life.
Through five dreams the narrative depicts the main character seeing the same woman recurring throughout his dreams. Her appearance and name are continually changing, but they are always seventeen and fifteen and the two characters never fail to recognize each other. A short story of love lost and found and an example of how dreams can stay with us and weave a rich tapestry of experience and characters.
