That's creepy
I found the noise btw, my phone was dying DX

It reminds me of a similar situation.

When I got my first gameboy, the first game I got was Pokemon Blue. At night, I'd swear I'd heard the little BLING noise it makes when you turn it on, and sometimes I'd hear battle music. I KNOW it wasn't on, because you have to walk around to get into a battle, and the gameboy was on my dresser. I know I wasn't crazy, because my little brother came in once and said, "YOU'RE NOT SUPPOSED TA PLAY THAT WITHOUT ASKING MOMMY!" I'm still a little creeped out by it.
