The dreams are still happening and Anna's still pissed. So things are going to get worse. As of Wednesday (whenever Anna rolls out of bed, prolly before noon) every source of water in the resort is going to disappear. Where'd it go? Into the guest suites. Every guest room and the hallways and the lobby will be flooded and will remain flooded. Wherever Petersen walks, he'll be trudging up to his knees in water. (The resort is still covered in green roses too, by the way, that hasn't changed.)
HOWEVER, whenever the employees need water (to drink, to shower, to cook with, etc) the faucets will work for them and them alone (not the guests and not Petersen). Anna's punishing Petersen, not her fellow kidnapees.
