Hi there, your husband seems to be suffering from what is commonly known as sleepwalking and sleep eating. Technically they are called somnambulism
and are a group of sleep disorders known as parasomnias
. It would help to develop a good sleep hygiene
and avoid any habits associated with loss of sleep at night and daytime sleeping. Good sleep hygiene handout at this website is helpful - http://www.canadiansleepsociety.ca/Map/www/pdf/brochure/normal_sleep.pdf . It might also help to consult a doctor if none of these suggestions seem to improve sleep. I hope this helps.
