I was coming home from the store at around 1:00 a.M. as i approached my house at here was a very deep bass him above me above the cloud cover. i physically felt a sudden drop in air pressure like i was being squeezed towards the ground. the him vibrated me and felt very heavy. it lasted about 45 seconds and then i could feel the pressure easing and the him drifted away straight up. it clearly felt like some massive object had been hovering above me and could have crushed me if it came low enough. i had a migraine for 2 days afterward.I don’t believe it was a weather phenomenon. it felt intelligent to me some how.
