ds gets them, but he has ADHD and they're unfortunately quite common in children with ADHD because attention and sleep are operated by the same part of the brain! They also quite often manifest in 5/6yo as the brain develops.
i would go through the whole 'sleep environment' stuff, just to rule out it being environmental or related to her school day tiring her out.
make sure her room is as dark as possible, that nothing on her nightwear is irritating her.. if she's getting hot/sweaty from wearing fleecy night clothes, switch to cotton.
make sure she's not eating within 2 hrs of bedtime so she has time to digest her food.
restrict games/tv in the hour prior to bed, keep her mind as relaxed as possible, so encourage book reading and cuddles...etc
During a NT, the best thing to do is change the environment. Take her out of her bedroom, into yours or downstairs, turn the light on, you're not trying to wake her, just alter her environment. Most NT present as them seeming to be awake, but in reality, they're still asleep, they won't make sense, questions will be answered, but garbled and nonsensical, returning them to bed too soon can prolong the tears/fears/crying/etc.
