Thirteen people in the article linked below recount their experiences of being in a coma, at least what they could remember of it.
Interestingly, those experiences varied tremendously, from "total blackness" in some cases, to the mind of one patient creating, and apparently then existing in, at least in his coma-dominated mind, a whole new separate reality, right down to the smallest detail.
And there was the account of one patient in a coma who claimed he seemed to be floating in the room above his body while looking down at it, like the reported "near-death" experiences of similar nature.
Really fascinating, though, is account no.7 in the article, in which a patient claims that while in a coma his mind constructed a totally new universe for him, with a wife, children, a job, and a "life" that seemed to him to go on for years.
Then, he claims, when he was taken out of the coma,
"I went through about 3 years of horrid depression, I was grieving the loss of my wife and children and dealing with the knowledge that they never existed. I was scared that I was going insane as I would cry myself to sleep hoping I would see her in my dreams. I never have, but sometimes I see my son, usually just a glimpse out of my peripheral vision, he is perpetually 5 years old and I can never hear what he says."A common theme in all of these accounts is, as I have alluded, the
extraordinary power of the mind to create various ways to deal with the unexpected and threatening circumstances that being in a coma had brought, whether through imposing a total mental blackout, or through the creation of an entirely new, though imaginary, universe for the patient to "live in" while in his coma state.
One can only assume, of course, that these reported accounts in the article are accurate, and whether they are anything more than just strange dreams the patients were having. Especially in the case of the patient whose mind supposedly created a totally alternate reality that, in his mind, lasted for years.
But it's arguably very true that a mind faced with the prospect of annihilation can, and will, go to amazing lengths to deal with the crisis at hand, attempting whatever it can in an effort to survive.
Interesting reading.
