Could have been seismic in nature. I experienced an earthquake in Fitchburg, MA. Shook the house I was in for long enough and in such a way that a primal alarm was set off inside me. Happened maybe 10 years ago. I checked online that same day and I was right about it being a small earthquake.

There were some strong wind gusts this morning, around 25/30 MPH in some places, maybe the wind was shaking your house?
