I've noticed a big increase in sychronicity and it is true that the more you acknowledge it, the more it occurs. I have a lot of like minded friends who are experiencing the same thing, yet a lot of people I know aren't. I guess they're just the ones who haven't woken up yet.
A couple of years ago I was talking to a friend about this stuff and she said to me why don't you ask for a sign to prove that it's real/working/whatever. So I did and the next day I was walking down the road to my house and I saw a small piece of paper lying on the ground, written on it was the word SIGN. I also get the phone call thing a lot, just as I am getting a friend's number out my phonebook to call them, the phone will ring and it's them, or I will send an email or text at the same time the recepient is sending me one. I find that at certains places like festivals and parties where a lot of people are connecting through music or good times or whatever, sychronicity is always a lot more apparent. I have loads of examples I could post here but I'll just go with the most recent one. Last week I was on holiday and eating out, my sister and I spent ten minutes talking about two very different and random subjects - sign language and how we'd both learned some at school and how my sister had forgotten all about learning it until now. We were also talking about a book called the dice man, a book about a man who lives his life based on decisions made by throwing a dice. Two minutes later a deaf boy came up to us and signed to us that he was selling something, a dice shaped lighter. I don't know hat the significance is but I bought the lighter from him anyway.
