I guess in the case I mentioned it would be what would be called dissociated trance. if you think of someone being hypnotised then apparently that is a similar mechanism.dissociate
It's apparently going into a different level of consciousness. So if you take unconsciousness on one end of the spectrum and being alert and wide awake at the other it is somewhere along that line.
I have never seen anyone do this from the outside but from the inside I can;t move or speak and if I do it takes enormous effort and feels in very slow motion. It also messes with ones understanding of the passing of time.
But there are also much milder degrees of it. For example similar to daydreaming but all the time in a way. So one is not very alert or present and are easily distracted.
And then there can be disconnections between us and our bodies or sense of selves and/or our environment.
An example would be actually looking at ones body from above. One can see the head and clothes and everything but from a distance. A milder example would be walking but feeling ones body is not really ones own. Or not being able to feel pain or sensation.
And with the environment other people can look extra far away and if one is looking at them through a tunnel. Or the world can look a little like an abstract painting. or ones hand or feet can look artificial and not look as if they belong to you.
The other one I have is where everything feels fine but I try to speak and my vocal cords just don't cooperate. The same happens to my hand at times and a few times my legs have done it and I fall. Its like they don't belong and i therefore don't have control of them.
Emotional numbness is another example. Oh and not being able to focus ones eyes and everything feeling dreamy.
Then there is the other type with is rare and is when there are walls that form between aspects of the personality and that means there is no awareness of what the other part is doing. And partial walls for some.
Apparently there are genetic and other things that predispose one to dissociate. Some people do and some don't.
