Last night, actually at about twilight, something hit the window that is just behind my desk. Really gave it a whack. Made a heck of a racket. I immediately went outside to see what it was. Thought maybe a bird had flown into it. I couldn’t find a thing that might have caused it.
About 30 minutes later there was another loud noise and the entire room shook. Went out and looked once more, but again nothing to be seen.
This morning I walked all around the outside of the building but saw nothing in the physical that could have caused any sounds like those I heard.
The strangeness continues.
