The phone number thing happened to me once too. A few years back when I was working as a dressmaker, one of my regular customers dropped off some fabric and a pattern. I said I'd give her a call as usual when it was ready, and she told me that she'd changed her number. I wrote the number down as she gave it to me, and I think I knew even before we got to the end of it what it was going to be - the number I'd had before switching phone companies at the begining of the previous year. I think it was determined to come back to me one way or another
My kids couldn't understand why I was so stunned by this, so I showed them the phone book, with all it's thousands and thousands of names and numbers inside and pointed out that any one of the people listed could have been allocated my old number, and that the chances of it having gone to someone I knew were slim - 'Put your finger on a page at random, and I'll put money on it landing on someone we've never heard of!'
Other similarly strange coincidences have happened to me, none that I can think of are number-related though. The mechanics of the universe sure are fascinating.
