睡了 一天 sleep all day

One ordinary Sunday, the husband woke up from sleep, had lunch with his wife at noon, the wife went out in the afternoon, the husband fell asleep again, a director came to see him....... In this ordinary day, the husband, wife, and director look like they care about and communicate with each other, but they are actually talking to themselves, and the most important thing is the end, the wife asks the husband to get up to eat. So is this husband＇s experience a dream or a reality?
