While it's not really comparable to this case I spent months in a coma. My wife tells me she was there 24/7 for the first week then hours after work every day. I'm told my family visited everyday as they had worked out a schedule. Every one them interacted with me or read to me or whatever. I remember nothing of it. I feel it did nothing for my recovery but who can say.

I remember only a very long nightmare I couldn't wake from. One bad dream after another. Normally I can wake myself from those types of dreams but this was permanent. Later I had to go to therapy to try to rid myself from those memories or at least learn to live with them. The therapist told me there was no way to tell if I had that experience during coma or during the time the - just short of od doses - drugs were withdrawn.

My waking experience was like swimming up to the surface of a clear blue ocean from very deep below. I remember hearing a tiny voice asking me to squeeze a finger and made a very small movement and remember a lot of shouting and stuff. Wife tells me everyone who visited me did the same thing every day but this one day I moved when she went through the ritual. When I became fully awake after all the drugs had worn off I realized I could barely speak and couldn't move my arms or legs. Months of rehab to follow. I still rage at movies and TV where a coma victim wakes and it's like nothing ever happened.

This was 10 years ago and as you can see it still effects me deeply.
