I'm hearing this weird sound but I don't know where it's coming from

Okay so at the weekend, I saw a picture of myself when I was seven at my holy communion dress. I thought it was really sweet as it had been put somewhere for so long and I hadn't seen it in a while.

I decided that I was going to take a picture of it using my iPhone as I would probably never see it again.

I went upstairs to where it was placed on the landing and took a photo with it. I was listening to a song whilst doing this when I heard a strange noise. At first I thought that it was my headphones or the music I was listening to but as soon as I took one earphone out I knew that it was completely the opposite.

I listened carefully and it sounded like a nursery rhyme that would play on a loop. This kept happening for five minutes.

I looked around and couldn't work out where it was coming from (I was on the landing). I ended up thinking that it was the photo itself.

I got petrified so I ran downstairs and told my dad. He followed me upstairs and it had stopped.

It really scared me though because I did end up taking both earphones out but I still couldn't work it out.

Does anyone know what I was hearing? O.O

It could have been an "audio memory" which came back into your mind, as a remembrance of when you were young, as in the picture you just found. Nursery rhymes from the past are still locked in your mind and this picture could have shook loose a whole lot of memories. Remember, you were very excited at the time, when you actually saw the picture of your holy communion dress, so that could very well have been the cause!
