I understand your thinking, I used to think that way too. I talked to my mother about it because my mother was in a accident and in a coma not expected to live or to ever wake up for 28 days.
My mother told me she was aware on some level; she knew when her mother was with her, she got to “know” certain nurses that were kind spoken. The thing she told me that I will never forget is that she had no awareness of the passage of time, she was in a fog like state and said the things like not being able to get up and do things, all the things you are concerned about- the awareness of that wasn’t there, she just didn’t even think about that type of thing. When my mother woke up she said she had no idea how long she had been in a coma, hours, days, weeks- no idea.
Three years ago my grandson was in a coma for almost 3 days and I asked him what it was like, he told me pretty much the same thing my mother said. He knew on some level that his mom and aunt were with him all the time, and knew hubby and I were there but were not there all the time. He is the most active boy ever, he is not a couch potato at all- he said he never thought about not being able to do anything- just never occurred to him.
My hubby was blown up by a landmine in Vietnam and told me he remembered floating up in the air, thought that was weird, didn’t know what was happening- then pretty much nothing for days. He did remember some awareness that things were going on around him but he said he never thought of what he couldn’t do, how bad he was hurt or anything like that until he was fully awake days later.
There was a woman in my state that was comatose and declared in a vegetative state for somewhere around 20 years and woke up- it was in the news for a while. She said she had no idea how much time had passed, to her it was like going to sleep and waking up the next morning. She did have some awareness of her family and music they played for her. In fact what she had a hard time with when she did wake up was that her kids had grown up and her mother, sister, etc. had aged.
It is a different state of mind, it seems it is not what we can relate to, people that are unconscious or in a coma don’t seem to experience the things that most of us think it would be like.
Thank you for relating your experiences. It must have been very painful to have to live with that. The descriptions of what it was like during the coma is definitely something to ponder about. Perhaps it is a defense mechanism your brain creates to prevent itself from going insane.
