Maybe that's true, but when I hear people say they always look at their watches at 12:34 or such a thing, I suspect (because it never happened to me!) it's probably something akin to the Baader-Meinhof illusion, "where something that has recently come to one's attention suddenly seems to appear with improbable frequency shortly afterwards." There are many similar phenonema humans fall victim to, thanks to our cognitive biases - our brains not as good at certain things as we'd like to think.

You tend to only remember what seem those unusual times. And the more you freak out about it, and wonder what the hell's going on, the more you remember seeing them, and the more you look..

It happens to me pretty frequently. In truth, I know that I look at the digital clock on my microwave probably 100 times a day.

It might also be precognition?

Or 12:34 or sometimes my birthday.

It is more likely that those are the instances you remember because they stand out as compared to other uninteresting instances. So you get the impression that the former happens more often.

Yes, I too am a fan of repdigits.
