http://www.newscientist.com/article...nded-between-life-and-death.html#.UzRnK1RMB5Y Please actually read it, even though it's pretty long. The benefits are too awesome to ignore. So, if this works then the possibilities are very interesting and potentially amazing as the technology could be used to suspend aging/space travel too in the not too distant future (~30 years, I guess.)
I don't have much to contribute as far as the science goes, but I actually think this was in an episode of House in season 2. The girl with cancer who started hallucinating.
Hopefully long-term suspended animation will be a thing when I'm turning 60+. If there's not some fountain of youth treatment/drug out by then, I'd probably consider freezing myself until there is something around to allow a much longer, healthier life. That is if I had enough money to afford it. Probably not cheap to have a company carefully monitor you for many years. And by the sounds of it, it'd be an almost instantaneous jump to the future since all brain activity will be frozen. You wouldn't be unconscious or be in a dream-like state. You would experience death (nothingness) until you were revived. So saying you'd experience anything is really the wrong description I guess. The scary part is that you have no idea if somebody will actually wake you back up. It could be an instantaneous jump, or you could just be dead forever. I can only imagine closing my eyes one second and the next second opening them up years in the future. Crazy stuff.
