Mind in coma

There is this awesome website: https://www.futurelearn.com 

Great teachers from different universities sharing their knowledge and way of thinking with us. Check it out, have a look. I probably will make later on another post about it.

I just joined a program called: “What is a mind?” Here is the video what brought up a question: https://view.vzaar.com/3767605/video

The question:

Let’s see the example, being in coma - Where is our mind? What if the mind experiencing new things, feeling, realising or knowing more as we “healthy” people do,  series of unexplainable happenings, but our memory can’t process it, or awakening is blocking these kind of memories so the person after coma feels as nothing happened. There must be for sure some experiences, researches about this topic, I’m just curious of your thoughts.
