My husband Z has night terrors. This was a great source of excitement early in our marriage.
The first time he woke up screaming about spiders, I turned on the lights and looked for spiders.
By the third time it was normal.
He usually doesn't remember anything the next day.
It's not always spiders, though. Sometimes it's a mysterious medical malady or some new and different creepy crawly. Not long ago he tried to convince me he was dead.
While I failed to convince him that he was indeed still alive, I did talk him into going back to sleep.
