It's called synchronicity. And now that you notice it, it will happen all the time. Welcome to the wonderful power of your thoughts! Your thoughts create your reality. Or as The Secret folks would say, your thoughts are attracting like thoughts to you. You are definitely in the right place to explore this. See the Intention/Manifestation section of this forum.
Here's what happened to me yesterday. I have a blog called Magic of Believing
. I wasn't able to post until yesterday, so I was about 5 days late. When I did sit down to write, I wasn't sure what to write about. In my email came a link from a reader to an inspirational video on Youtube. Bingo. I blogged about that. I changed the title several times and finally decided on Don't Give Up. Last night I finally sat down to watch the new X Files movie a friend had burned for me. The title of the movie was I Want to Believe. And the theme or message of the movie? Don't Give Up.
It's kinda freaky at first. But like I said, when you start noticing these little 'coincidences' , you'll start seeing them everywhere.
Have fun with it! There's a lot more to learn.
