Anything you got on being in a coma!
Hey! I am writing a book (slowly but surely!) and I am doing research about comas. Anything and everything, really. The different types and levels, what happens in each level, what type of machines one might be on with them, etc. Basically, if anyone has any sort of info on coma patients from whatever point of view I am sure it would help.

I don't know if this is relevant, but there was a fantastic TV show called Life on Mars, which was essentially a British TV cop show all set in the mind of someone put into a coma after a car accident. Set in the 1970's, too.
There was quite a lot in-depth though of the person in the coma trying (and usually failing) to make contact with the outside world.
If you're interested, then I highly recommend you either buy the DVD or, if you can't play region 2 DVDs, torrent it (here's the link).
Not sure what the policy on linking to torrents is, if I'm doing something wrong then tell me.
N.B. This person is also hosting the videos on Youtube, but each episode's in about 5 parts.
I don't know much about coma's aside from this; a coma is a lot more severe than is seen on television or in movies, and The Odyssey was a crazy-awesome show. At least at my age when it was popular.
Keep life as it is in fundamental simplicity and
clarity will arise itself. Only by doing nothing
will you accomplish all there is to be done.
