Troubles in Otari Part 3 (spoilers)

Question regarding the nightmare terrain in Part 3 of Troubles In Otari.

Just curious how people handle this or if I’m not understanding it properly. It spans 60 feet out from the entrance, but most PCs move at 25 per action, so they would be through it in one turn. Unless the terrain acts first, how does this actually affect anyone? How have people run this before?

Sometimes posting a question can bring its own clarity. And sometimes bring up another one. How do folks handle it if the party simply says “we close our eyes and run for it”?
