desenho animado dos anos 90 sobre guardiões contra pesadelos

Talvez seja o Capitão Zed e a Zona Zee.

Captain Zed and the Zee Zone is a short-lived CITV television series, airing in the United Kingdom. When children go to sleep it is Captain Zed's and his Partner PJ job to prevent children from having nightmares in the dreamzone. The 26-episode series was animated by the Collingwood O'Hare studio and co-produced by DIC Animation City & Scottish Television (now STV Central) in association with HIT Communications PLC.

O capitão Zed voou em uma espaçonave em forma de travesseiro.

Seus inimigos principais eram as criaturas que mudam de forma, Mutter e Snort, que queriam causar pesadelos para todos.

O show foi para crianças mais novas e durou apenas uma temporada.

Poderia ser O Dreamstone ?

The Dreamstone is set in an alternative world called 'The Land of Dreams,' and concerns itself principally with the struggle between good (personified by The Dream Maker, a Merlin-esque white magician), and evil (personified by Zordrak, Lord of Nightmares).

....

The Land of Dreams is populated by Noops (the humanoids of the land, who live and work like humans in a town called 'Noopville') and Wuts (the defenders of the land, who fly around on leaves and ward off Zordrak's evil forces with staffs that have orbs of light attached to them, through which they communicate).

Um pouco menos provável seria Patrulha da meia-noite: aventuras na zona dos sonhos .

The series tells of four children and Potsworth the dog who live in the same neighborhood. When they go to sleep at night they turn up in the Dream Zone where, as the Midnight Patrol, they are appointed by the Grand Dozer to protect it from nightmares and other threats and are given their missions by the Snooze Patrol. Their main enemy is the Nightmare Prince.

Whilst they are in the Dream Zone, the five have special powers. Keiko has a flying skateboard; Carter can draw anything and then have it come to life; Nick is super-strong and is able to fly; his stuffed toy Murphy comes to life; whilst his cynical sister Rosie tags along. Potsworth himself acquires the power of speech which enables him to complain about the way he is treated in the real world, and make wry comments about the kids and their own attitudes and relationships. The cartoon Potsworth had a very "English" accent, even in the American version of the programmes, reflecting his real-life counterpart's British origins.

Eu não encontrei nenhuma referência para as crianças morrendo se acordarem, mas se o Grand Dozer acordar completamente, a Dream Zone termina.
