I heard a sound that made think sheets of thin ice were falling off the west side of my house
Delayed Sound
Observation
Yes
Remarks
First the south wall of the south face bedroom I was in started making wall-cracking noises like the house was shifting. Then I heard louder sounds coming from the bedroom just north of mine that made me think someone was in the room moving things around! I sat up to listen, but it ended then. I did not see anything so my answers to the visual questions were just to get me to the audio info
