Weird way I created to escape nightmares or situations I do not want to be in dreams

I was thinking a lot about sharing such things with others, but I think maybe I am not alone and someone is doing the same. Sorry for my english, it is not my primary language.

When I am dreaming sometimes I end up in situation where I can feel something is wrong. Lets call it sense of danger or something. For example, in most cases it is light switch, as I turn it on and the light is very low and slowly dying or switch is not working at all, I know something is wrong and my nightmare is coming. Right in that moment my dreams where I am just observing or doing things automatically and not lucid dreaming switch something in my subconscious and I know I am dreaming and that nightmare is coming. I can try to describe what I am doing in that moment as best as I can, but maybe it is crazy. It is just as I rip my face out of my dreaming myself and wake up. Like splitting my conscious out of dreaming myself. But as I do that I wake up but my body is extremly non responsive and I have hard time to even open eyes in most of cases. But it slowly go away, I guess it is some sleep inertia from this not normal waking up procedure. I had a lot of nightmares as small kid, so I guess my brain train some kind of alert, when it sense some danger ti will automatically activate.

I can recall that I used it also in some situations I did not want to be but it was less frequent, it is mostly happening in these pre-nightmare situations.
