Has anyone else woke up and found themselves choking their partners?

When I first got married it was the first time I shared a bed with another person on a regular basis. In the first few months I would wake up in full fight or flight. Sometimes I would wake up sitting up super fast, sometimes I found myself springing out of the bed before I knew what was going on. One time I even found myself choking my wife before I could recognize what was happening. It was really scary and I felt a lot of shame about it.

The weird thing about it is that happened several months before my CPTSD symptoms started showing up proper. I’m divorced now, but I still find myself thinking about those times and wanting more understanding of what’s going on. Has anyone else experienced this kind of thing?
