Around every 3 weeks my son is okay and then all of a sudden complains of having a weird feeling and his head hurting. He also shows cold/flu symptoms ( hot, tired, headache, bright red cheeks, generally feeling unwell) he goes to bed perfectly fine but about an hour later he wakes up and through crying and body language we can tell he’s had a bad dream, he gets really upset and covers his face and doesn’t really know what to do with him self and just keeps crying. It’s like he isn’t properly awake but if you asked him questions about what day it is, what he’s doing tomorrow etc he knows the answer so makes me think he is awake. He also says that everything seems really big and fast when he moves after this happened and then eventually just turns over in bed and goes back to sleep. I’m wondering if this could be a neurological issue? He used to have night terrors when he was a toddler however those have passed as he has gotten older. The pattern and complaining of feeling weird in his head before it happens is what worries me. Any advice would be appreciated.
