There is no such movie as Men In Black.
The entire human race has had their collective memory altered, by similar means to those shown in the film we all think that we have seen. We have all been made to forget something very terrible indeed. The people who have changed our memory have told us about a movie which we have now imagined to be real, so that the possibility that our memories may have been wiped out seems the stuff of light hearted Science Fiction. Whenever you think that you have seen the movie, your memory has been rewritten again. You have re-learnt some gigantic, terrifying truth, and somebody has removed it from your mind. At some point in the future, you will forget about reading this node. That will not be an accident.
How do I know all of this? I do not know, I can’t remember.
