A childhood belief about magic tricks

When I was about 7, I had a poster on my ceiling of one of my favorite child actors, one I had the biggest crush on. I would talk to the poster and sing a specific song to it- "Change the World" by Eric Clapton. I was under the steadfast believe that as I was singing it to his poster, wherever he was he was catching faint echoes of it, and that it would haunt him and be a mystery to him until one day, when (not if) I was to meet him in person when I was also famous and working in the movies, I would very casually and knowingly slip the words "Change the World" into the conversation and he would immediately be flabbergasted as to this stranger knowing about the song that has been following him for so long. Of course, thereafter I win his heart etc etc and move on to more normal fantasies, but for some reason the absolute trust I had in the fact that he could hear the song was so casual and easy- I have a hard time actually 'feeling' the disbelief to it even now, when I know the truth.
