Sometimes I get headaches that last for two weeks straight, and one day I'll wake up and find that I seem to have slid between universes in my sleep. Posts here change or vanish, certain stores don't exist or aren't where they should be.
As far as more common examples go, for instance I remember C3PO being completely gold and Darth Vader saying "Luke, I AM your father!".
That kind of stuff happens to me often. I joke that it's my memory, but maybe my memory isn't as bad as I think it is. Could I be losing my phone because I keep switching universes? LOL. Who knows.....
And either Words with Friends literally changes its dictionary every other day, or something strange is going on. One day Wo and Wa are words. The next day, they are not. So, I keep trying them regardless. It happens too often to just be my memory. I'm too young for alzheimer's (I think).
