Hello, Kathy, long time no chat/no music request.
In any event, I believe the "deja vu" scenario comes from previous had dreams and when the reality kicks in then you just pause for a second or two, scratch your head and ask yourself "been there once before"...what's up with that! Not to mention, that at times, I refrain to do things that the "deja vu" sez' careful with that! Really scary stuff at times!
Best Regards Kathy!
And best regards to you, too, danmar....the "deja vu's" are so real, and yes, scary at times.
