Help me identify this movie

[Dickey]

Saw a movie a couple years ago, I think it was on TUBI. I need to know if anyone knows the name, and the plot went something like this: A girl wakes up on a beach somewhere, but doesn't know who she is or how she got there. There is a house on the beach, almost at the water line, she goes in & all kinds of strange things start happening, but the strangest of all is the sun is coming up, but starts to set earlier & earlier every day, till there's nothing.
Anyone know the name?
