Quoting Neurogenisisis: "I had a 2 weeks period of a stomach flu that completely destroyed my health for a year's time."
I wonder if you caught the same virus that I did in this infectious episode? The virus I caught (which was likely a nasty strain of coxsackievirus B) permanently induced both anhedonia and blunted emotions in me. See my website about this virus here: https://chronicsorethroat.wordpress.com
Also, I later then developed chronic fatigue syndrome (ME/CFS) from the virus, and this in turn led to a loss of my spiritual sense, and my conscious sensibilities. I think what you are describing as "an atmosphere-feeling" is the way the brain can produce a gestalt of our sensory experiences, to create an overview or "distillation" of our experiences and circumstances that results in an overall tone, feeling or "vibe".
I lost that ability to create an "atmosphere-feeling" in my mind after I developed ME/CFS. I am still aware of the circumstances around me, and still aware of my sensory experiences; but those experiences do not get turned into an holistic "atmosphere-feeling". I just perceive the sensory experiences as cold dry fact, but they are not embellished with this gestalt "atmosphere-feeling".
