I don't recall if there was anything that scared me as a kid to the point of nightmares or anything like that. I do agree that Angelica's Nightmare is creepy and unsettling. The Wormy closeup never really scared me but I can see how it might be startling to some people. As long as we're talking about scary moments in shows, does anyone remember the Rugrats episode "In the Dreamtime" (I'm not Tommy/I'm not Stu)? Sorry if I scared anyone all over again. That is definitely creepy/unsettling but I might've been a bit too old to actually be legitimately scared by it. I actually still find that scene a bit unpleasant to watch and I'm 26.
