My wife had a couple of rotten dreams about me this week. I had to reassure her that they were just dreams. Boy did she get mad at me for stranding her in New York City and looking at another woman's boobs on her phone, though!
This has happened to her before, and it is a bit of a pattern, but usually only lasts for a day or two and usually not more than once every couple of years. Hopefully this is just a temporary thing for your husband as well.
