16-Year-Old Girl With Amnesia Wakes Up Every Day Thinking It’s June 11

When this 16-year-old wakes up every day she believes it's June 11, 2019. For her, every day of the year is the same day. It might sound a lot like the plot of the movie "Groundhog Day," but the rare form of amnesia that Riley Horner has is much more serious. June 11 was a special day for Riley. She was attending a dance in her Illinois hometown, but the fun turned to fear when a boy fell on her. She ended up hitting her head and being rushed to the hospital.
