Yes. Just google "hallucinations during deep hypothermic circulatory arrest". Not hard to find all kinds of info.
I've read about near death experiences before, so the information at the link you provide is nothing new.
BTW, according to science, absent brain waves/brain activity there are no dreams. Yet the testimony of real and sincere people indicates they 'remember' something that happened to them while in a brain waves-less state. Having the last word seem very important to you so I will withdraw from this thread and leave you to your needs.
