I, also, have been noticing the numbers 234 or 1234 with increasing frequency whenever I would check the time.  It has also happened during the night....I would wake up and look at the clock and it would be 12:34 or 2:34.  

I have been noticing 11:11 but not as often.  It's encouraging to know that others are experiencing the same thing.....

Maranatha!
