Hayley, I too have experienced something with 444.
Within the time frame between 1/18/07 to 2/27/07 I woke up 4 times at 4:44 each morning.
 
1/18/07  444 then 4 days later
2/22/07  444 then 4 days later
2/26/07  444 then 1 day later on
2/27/07  444
 
The next thing that happened was I had a quick vision of my 95 pound black lab jumping a really really tall fence.  It would have had to be supernatural for her to jump that high.  This was 2 days later as I fell asleep.
 
 I haven't woke up at 444 since then.  The really weird thing is that last year the 222 was during Feb. and the 444 this year was also during Feb.
 
I don't know what any of this means.  But last year I was awakened at 2:22 3 x within 1 weeks time on 2/16, 2/20, 2/21 then the next day was Feb. 22.or 222.?  hum?.
