When I was about 9 or 10 years old, I saw a film with my sister about a guy who died and went up to heaven, where there was a queue to get sprayed with something that erased your memory of the past. In the film, the guy was so upset to have died, he bypassed the queue and got sent straight back to earth, where he was born again as a baby and grew up remembering his previous life. 18 years on he was still tormented by these memories and sought out his 'widow', who still left biscuits by his photo every night, and tried to convince her he was her husband.
The film really bothered me and for a while I struggled with the possibility, upon hearing someone we knew had died, that they were coming back to earth, and worse still, would hold all their memories and try and rejoin their former life.
