Again you seem either unable to grasp what I am saying or are deliberately trying to avoid it. I am saying that people have reported ACCURATELY what was going on around them or in the next room while they were dead or comatose on the table. NOT they imagined they saw an image that didn't reflect reality, they accurately reported WHO was in the other room, WHERE they were sitting and WHAT they were saying. These cannot be simply things made up in the patients' minds.
Let's put it this way. If you put someone in a closed room in a building they've never been in before, then put 5 people in another room down the hall and the first person later told you that while he was in the room he saw some people in the other room, you would say, "That's great, you imagined it", right? Now, what if he told you how many people were in the room, where they were sitting, what they were wearing and what they were saying, and it accurately matched a video you had taken of that room? This is very important and you need to be completely honest. Don't try to dance around it, don't mumble something about medical causes, what would be your reaction?
Likewise, if the first person told you that there was a shoe up on the roof of the building (remember, he's never been there before), and you went up there and found that shoe exactly where the person said it was, you would, if you were honest, believe that the person actually saw it. Again, this is all contingent on you being honest.
Back to real life, if a blind person reports that she saw not only everything that was being done to revive her, but that she saw a pen fall out of a doctor's pocket, correctly identified where it rolled to and where he picked it back up, what would you say? Remember, she's blind and saw these things.
Of course, you could invent conspiracies about having multiple people poised and ready to go to feed the patient information or to place objects where they would later be found, but that's kind of ridiculous because people don't know when they're going to die on the operating table, and in many cases the doctors and nurses would have to be in on the whole thing.
I'll give you link to get you started because I don't trust that you will actually do any research on your own. Now don't think that this is the total of the experiences people have had. It's just a snippet.
