I'm looking for opinions here. First person POV, comic urban fantasy, noir-ish voice. My character has been flatlined once before and has only hazy recollections of what happened when he was dead, and all of that will be exposed in conversation, flat-out exposition, or whatever, not experienced "on-camera." However, towards the climax of the book, he's going to have to commit suicide with the aim of being sent to Hell to rescue a girl who shouldn't be there. While there, he'll meet a demon who will tell him some Truths about the Way Things Run. Now, since he doesn't remember the details of his first trip to the afterlife, I'm thinking that this means that there's a sort of protective barrier, either automatic or induced, to prevent people from bringing back accurate memories of what happens after death (it's pretty comically fucked-up), which means that the demon could say something along the lines of "But it looks like the CPR is working. Don't worry, you won't remember any of this," and the MC comes back to life with a fleeting impression like when you wake from a vivid dream which is gone before you make it to a pen or the toilet or whatever. The question is, would you find it unsatisfactory or irksome to know details of the character's (after)life that he is no longer in possession of, or do you think it could be pulled off? I can think of one example from a commercially successful book where it happened, but it was A) Close third, and B) right before the character "rode off into the sunset." Since the author is now deceased, there won't be any sequel to have problems with. Any and all input is appreciated.
