This rather unreported phenomenon happened to me some years ago and it was bugging me so much I actually "appealed" (to whomever might be listening :) ) for it to stop...and it did. I started seeing my date of birth everywhere, I wasn't looking for it, it just kept presenting itself to me. And the effect became greater and greater.
My car trip-meter stopped perfectly on the number and never moved again. I bought a house to renovate and the old deeds came through the letter box one day (more than 100 year old deeds). I was shocked to see that the number of the house had been changed many years ago but was originally my number. Couldn't believe that either.
I was in a relationship with a woman who was only interested in fleecing me and she did, more or less every penny. She then immediately took up with a business man who I knew of but did not know personally but it was necessary to have some communication with him through a solicitor (I was asking my ex to return some of the money I had lent her..many thousands...she wouldn't, she said it was a gift).
I didn't know where this guy lived so I went to the electoral role and I discovered that his number on the role (two digits) was the same as my date of birth. My ex refused to give me anything (she'd had many thousands out of me possibly nearly 20). About three months after this, tragically he was killed in an accident which of course I did not wish on him.
This stuff went on and on, far too much here to tell of. I'd wake up in the middle of the night, look at the alarm clock, bang there it was. Sometimes when I woke up, I'd deliberately avoid looking at the clock for a few minutes but then when I looked..bang again, there it was. I don't have a rational explanation for this but I personally believe 'something' was playing games with me. It more or less stopped when I consciously asked it to. If someone had told me the same story before this happened to me, I'd have said "pull the other one !"
