A few weeks ago our 8 year old daughter started to have a "night train" of thoughts and images, small videos, occasional math equations, and so forth, become so intense that it is hard for her to sleep. She said, and I am quoting her, that her "computer is going through past events and thoughts to find material for dreams" and that she cannot stop her brain from making this search until it is complete, which makes it hard to sleep.
For the third time this week, she is falling asleep in the living room in front of the TV after moving downstairs at 11pm, unable to sleep because of her brain's inability to shut off. She has had a wonderful happy week, spending three hours a day in art camp with her favorite teacher and her best friend. She is cheerful and happy in every other way, and the night train started really ramping up a few weeks ago.
Our other child (NT) never mentioned such an experience, and frankly, this scares me (I have medical anxiety).
Is this typical? I can't find anything about it, and "night train" is her own expression for this experience. Another thing that really scares me is that tonight she told me she had a nightmare last night that an alien was invading and hurting her. Naturally, I am worried that her other symptoms may be a sign of something physical going on, especially since her waking life has been so good.
She has developmental coordination disorder diagnosed, also Asperger's and very physically clumsy. She is gifted and has auditory processing disorder.
Is this typical for Asperger's syndrome? Or do I need to take her to a doctor to be more thoroughly evaluated.
Thank you for your help.
