Grace Vickers spent almost two years at the Melville Unit from the age of 16.
The now 22-year-old said the worst part of her experience was being restrained for forced tube feeding.
The Aberdeen University student said she was fed through a nasogastric tube “at least three times a day” during most of her inpatient admissions, which she said “often” involved restraints.
“I can’t tell if it’s more traumatic when it happens to you or when you witness it happening to someone else,” she told BBC Scotland News.
“I still get nightmares now – like the screams and people pleading.
“It never leaves you.
“That’s probably the most traumatic thing, especially (nasogastric) feeding because it’s painful.”
She said that, as a result of her admissions, she now suffered from complex post-traumatic stress disorder.
The inspection report acknowledged improvements since Grace was a patient at the Melville Unit.
Reflecting on her time on the ward, the student said: “Every single day, as soon as you wake up, you’re hearing someone else screaming and then later it’ll be you screaming.
“It put so much anger and fear in you. There are some nurses who made a great, good difference to my life.
“But it’s hard to be grateful for that when it feels like the rest of my life, I’m just going to have to be dealing with the things that I’ve seen and heard and been through.”
