Sandra Bullocks plays a good-looking mother who is visited by the most awful kind of deja vu experiences you can imagine.  She no longer knows what is real and what is simply a hallucination. I was moved by the film because it artfully highlights how we can quickly fall apart when our brains are no longer able to provide one coherent take on reality in which earlier events happen earlier and later event happen later—where we can remember things in the right order. Speaking of deja vu moments. The other day I sat next to a lady at dinner and I thought I had seen her many times. My brain is now scanning memories for her Doppelgaenger. She agreed to meet her if I can find the twin.  I am curious to see their reactions when they first meet because they look eerily alike.  Twins separated at birth without them knowing it? Uhhh.
