My friend told me a story about her sister and brother-in-law.
The BIL had trouble sleeping through the night. He was in the Navy and worked at night.
One night the BIL was having trouble sleeping and tried not to wake his wife. He went into the bathroom and fell asleep on the toilet. Apparently, that was not so strange for him to do that.
His wife was unaware that he had gotten up, and during the night she went into the bathroom and when she sat down, she sat in her husband's lap, and it startled her awake and she screamed and he screamed.
