I had those as a kid. That bit about not remembering them is a total lie. Mine lasted until I was 8 or 10, but still appeared sporadically (once a month or so) well through college.
If she's verbal enough, ask her to talk about what she's seeing and hearing and make notes. Then, if it's possible, work those sorts of things into imagination play / story time so she can address them with her waking brain. Mine were mostly loops and once I found ways out of the loops, the terrors stopped.
Those aren't night terrors. Those are nightmares. Night terrors happen during non-dreaming sleep. The child is never awake.
