My grandfather passed away in 08. He was a big fan of opera music and would blare it in the morning if he and my grandmother ever had any grandkids sleeping over. It was a good wakeup alarm. About a week or two after his funeral, I was lying on my bed when I began to hear a scraping noise. I looked in the direction the sound came from to see a clock radio on the top shelf of my desk turn to face me, sliding across the desk in my direction, and it started playing all by itself. The music it was playing was opera music.
