Years ago I had something very similar......I experienced this about 18 years ago and then again about 7 years ago. For me, I believe it was med related. I did not stop taking the med but adjusted and it went away. Is it possible you are having night terrors and are still asleep partially when this happens? That was the case for me. I’m so sorry you are experiencing this confusion, it can really murder a person. (((Hugs)))
