Trifling and Transitory Brain Cramp
In a nice bit of coincidence, I found a link to this article about deja vu only moments after a fairly strong deja vu experience at work. (I was typing klngRightLeft as a variable name in my program and it triggered a deja vu in which I was hollering at somebody about what a stupid variable name that was.... Sadly, all too plausible given my mood at work these days.) Anyhow, the article doesn't really have any answers, but it's kind of neat that someone is looking into it again. My deja vus always feel as if they are related to a previous dream, not to a previous actual experience. And usually I find myself fighting to make sure I do something differently, because usually the situation in the dream evolved unpleasantly, usually because of something I say or do. I like the idea of a brain cramp, though:
The Victorian-era British psychologist Sir James Crichton-Browne suggested that deja vu is caused by a "trifling and transitory" brain disorder, "like cramp in a few fibers of muscle."
