The problem you have tried to describe, doesn't appear to a nightmare. Its more closer to being a night terror. Please understand that such complains are very common and increase at the time of stress
. People generally don't discuss them as they don't cause any problem for themselves. Epilepsy
/ seizure disorder
is another concern and he should be investigated by an EEG. There are many unanswered questions in your write-up. But one thing is for certain that your husband surely need some help from a psychiatrist
. Please ask him to visit one who would like to explore many his areas.
Hope this answers some of your questions.
