Planet i. - Level I of Recovery

While I am lying down, my right cheek gets randomly tensed, and I experience sensations of tickling throughout my body. Fight or flight.

I keep on swallowing involuntarily and if I try to stop swallowing I get panicked.

I can catch my thoughts wondering around. I sometimes feel as if I am thinking of everything at the same time; my thoughts annul each other and I almost get empty. Is this rest and digest?

Is nervus vagus the answer to experiencing Level 1 of Recovery?
