Yes....sound can be weird.
My stereo is at the end of a longish rectangle of a room that includes my kitchen off to the side creating a bird's eye view "L" shape.
I was at the stove off in the kitchen listening to "Little Village".
As usual, it sounded like music being played in the adjacent room with sound "blowing past" the open area leading back into the main sound room.
All of a sudden, I hear a Ry Cooder guitar note coming OVER and BEHIND my RIGHT shoulder about as far away from speakers as possible. Now since the speakers themselves were blocked by two walls it could NOT have been a direct note from them, but an echo that sounded EXACTLY like a true note.
Now the weird thing is that this is repeatable. I can cue up the disc...run back into the kitchen...stand at the stove....and when Ry hits that note it will always sound like a fresh note coming over my shoulder.
I imagine if I put up a new painting or rearrange the furniture, this effect will end....but it's pretty cool.
