Ran the gamut here myself 111,222,333,444,555,411,414,717, 737,711,911,811,1111,1212 and lately the mysterious '616' on the digi-clock, I kid you not! I did not really see anything like this before 911 tho. Not that I recall...nope.... but definitely after 911! Hm....possibly a count down of sorts? Or did 911 start something and the cosmos is trying to communicate with us somehow numerically? Still have not figured what they mean tho. Probably some kind of etheric code....kinda like the crop circle thingy.
