Describe a truly terrifying experience that Really happened to you.

My family comes from a very isolated place, and because of that, my 96-year-old grandfather needs company. Every other week my parents and I usually go there to take care of him. The house is in the middle of nowhere and the nearest neighbor is 5 km away. One night when we were sleeping I took my medication That emphasis makes me sleep like a rock.We went to sleep at 8 PM when I suddenly woke up at 2:30 AM with a strange feeling (I can't explain it) when suddenly I started hearing something banging on the window, something like some bird which is not uncommon.But suddenly things started moving very fast, and then it just stopped.But it wasn't long before I heard someone screaming in the middle of nowhere; someone was screaming in an abnormal tone, as if it were a human imitation. But then it stopped; nothing else was heard that night. When I asked If anyone heard anything, nobody heard anything. Sometimes I wonder if I was dreaming.
