You probably woke up many times and glanced at the clock, but because it is a number image with a pattern, it locks in the mind more than other times so you are more likely to remember that versus say, waking up at 12:15. After you noticed it the first time, you probably thought about it more than you realized, especially with all the internet stuff about it, so subconsciously, your mind is now looking for that pattern.
It is akin to buying a car, suddenly you see the same model every where. I recently bought my wife a new car, a model that is not very common (both from price and that the closest dealer is an hour away), yet on the way back to work from lunch, I saw three on the road. I rarely noticed it before. My mind looked for it and was more aware.
I guess, it’s the mind playing tricks, but like I said I never remember waking up to see the clock at 11:11 in fact I never usually wake up,and when I do it is usually after 2:am...
I see 9:11 (digital clocks) more now. Have been seeing the pattern since 9-11 happened. I don't doubt what you say one bit.
I use to wake up late at night to go to the bathroom. I thought I had a “going” problem but then my doctor told me I had a “growing” problem.
