Pretty much all the Hell segments are shot with a sort of deranged creativity (which is appropriate for Hell of course) that would be particularly troubling for pretty much any normal child, so the fact this stayed with you is very much the same for any other kids who were born in the mid 80's- it happened to me too, though I was also one of those 'Tales from the Crypt'/Monster Joke/Monsters and Aliens/Reads-lots-of-Books kids so I managed to flip the trauma into appreciation fairly quickly.

some of the big hits for me on this topic are: the bathtub scene from the IT miniseries which I walked in on one night while staying at my uncle's place when I was maybe 6 or 7, this random moment from the Alien ripoff Leviathan where a monster's arm is sliced by an elevator that I caught on USA one night a few years later, and this Christmas-time dinner at a neighbor's house where one of the TV's in a corner of the house had The Shining on and I kept going back and forth between the party and the movie and I think my combination of confusion, horror and fascination with what I was seeing actually inspired my interest- I think I was no older than 9 or 10 for that one.
