Just to throw some confusion into this I did not hear the tree fall. But The Wife says she did.
Reminds me about an experience I had years ago.
Christmas morning about 2am I hear a loud bang outside. I get out of bed and look around out the window and don't see anything. It's dead out there. The lady says she didn't hear anything, but we were both sleeping.
And for more context, I sometimes get "exploding head syndrome" where I'll wake up suddenly to the sound of a crash or breaking glass, when in fact nothing is happening. So I just wrote it off.
Get up in the morning and there was a massive chunk of ice that went clear through the windshield of my car. Completely caved in.
We had just started renting the place and we were not warned that massive ice dams could break free and crush your car. "Didn't I mention that?" Said the landlord. No. No you didn't.
