Whenever I heard JW's say regarding the resurrection and those who have died " Their last thought.....will be their first thought ".
I used to say, " What about those who were killed in a car wreck....does that mean will they wake up screaming in terror? "
Then at one of the assembly dramas back in the 80's, they opened with the sound of skidding tires, busting glass and someone screaming in horror. I can't remember exactly how they worked it out but basically a woman came running onto the stage which was set up to look like the New System (flowers, bowls of fruit etc). She was was supposed to be the one who had been screaming. She came on stage all freaked out and wondering where she was and what had happened. Apparently she had been killed in a car wreck back in the old system. Everyone on stage ran up to her and welcomed her to the new system and explained that she had been resurrected. It was pretty sick and weird.
Anyway, that blew a hole in my little answer because yes....according to the society, people would be resurrected not realizing they had died and thinking whatever was on their mind at the moment of death. ( a comforting thought huh?)
