Here are a couple that happened to me. Neither are explainable but freaky anyway.
One night I was in bed sleeping when I was awakened by a rush of wind across my face. I looked to see if a window was open and they were not. While looking toward the window which is back-lit by our yard-light, I saw a bat flutter across. That was freaky as bats in the house freak me out.
Another time I had been in bed sleeping when I was awakened by the sound of thunder in the distance. I decided to get up and close the windows in the house as we have double-hung so it can rain in easily.
I was laying there listening to the storm when I began to notice a different sound from the thunder. Instead of the lightning flash/thunder rhythm, it seemed that the thunder was just continuous.
Curious, I got up and looked out our bedroom window, which faces toward our yard-light. When I did, I noticed the dust, leaves, and other debris whirring across the lawn in a rather large arc and then lifting upward. The small trees were not whipping back and forth in the wind but rather just pushed to one side and held there.
Bear in mind that this was about 4:30 am and I was not fully awake when the first thought in my mind was, "Wow! What a big dust devil!" Then it hit me. I was looking at a vortex on our front lawn! I woke my wife and we each grabbed a kid and headed downstairs to our basement.
I've never heard wind such as that ever before or since. We huddled in the basement, listening to the storm with the wind and rain. It was very loud. Suddenly we heard a crash and saw water running down along the basement walls. My wife said, there goes the windows. We fully believed there was no longer a house above us.
Suddenly, the wind stopped and it got dead quiet. We waited for a couple minutes and the wind started all over again. I figured that was the eye of the twister going over us. When it was all over, we went upstairs and there were no broken windows but the kitchen floor was wet all over.
Earlier that day, we had a contractor strip the siding off our house in preparation for new siding and the crash we heard was their scaffolding. The storm blew the rain right through the house wrap and walls. There was an older willow tree, approximately 4' in diameter, about 50' north of our house that was twisted like a cork screw about half way up and laid down on its side. Other than that, no serious damage.
That was as close as I ever hope to get to a tornado ever again.
