UGH I Just Got the Creepiest Feeling That I Have Been here(predicate) Before Dj vu and the Brain, Consciousness and SelfWe have all in all some hold of a feeling, that comes over us occasionally,, of what we are verbalize and doing having been said and done before, in a remote time - of our having been surrounded, low-key ages ago, by the same faces, objects, and circumstances - of our knowing perfectly what will be said next, as if we suddenly remember it (Dickens in David Copperfield - chapter 39 (1)) It happens to me and it has believably happened to you.
