The Ultimate Dream Warrior (Freddy Krueger x Fem! Patient! reader)

After a crude suicidal attempt, Y/n was sent to the Westin Hills Psychiatric Hospital by the officer who saved her, though, she's not appreciative of his gesture and loathes the hospital she got thrown in. But it gave her the opportunity to befriend a group of teenagers in the same predicament as her. Her protectiveness grew on the first day and bonds were structured, being twenty-five, the teens saw her as the mother of the group; the one that always treated them well and held them close when they were at their weakest.
But, what happens when a new therapist comes into the hospital and the teenagers are having nightmarish dreams, even Y/n herself? How would she take the situation and protect the teenagers she cares so deeply about?
How would the Springwood's Slasher react upon their first confrontation?
