I just went through what my doctors referred to as "long COVID brain fog". It is a surreal and completely debilitating experience, which robs you of basic fundamental cognition and puts you in a delirious state of complete confusion devoid of emotion and self awareness. #COVID19
I would wake up lucid, but after a few hours my mind would drop in the fog. It's tricky to explain, but the individual in your mind that maintains your agency, your personality, your desire, and your purpose in life becomes disconnected. You become a walking robot potato.
