Story: Deja Vu

I had this idea relating the common experience of deja vu to a physical event. After all, there must be an explanation for it other than just a glitch in the system. I couldn’t really come up with a story where this idea might play a critical role in the plot so I wrote a story echoing my experiences with making presentations at scientific meetings. This was always terrifying for me, especially because I always had pretty weak and mundane material to present. Am I on to something with this idea? Maybe, but I don’t have the mathematical chops to prove it one way or the other.
