A grieving mother was amazed to receive letters from her late daughter, months after she passed away from stomach cancer at age 21. There was something extra unique about the mail, however: The letters were addressed to her daughter’s future self.

Miho Nakamura wrote the letters to herself as part of a class assignment when she was 15 and 17 years old, her mother Sachi Nakamura told Buzzfeed News.

Some of Miho’s classmates commented to say they’d also received letters from their younger selves.

We hope the letters brought Sachi peace and comfort.
