Yes! His fiancée in his mid-twenties died after a car crash where he was driving the car. Even into his forties, he's still having nightmares about that crash and her death. Over the years the nightmares have become less literal and more abstract but as June (the month she died in) approaches they become more literal. He goes to visit her grave every year and during that time he has intense nightmares that usually result in him not sleeping.

As far as dreams go I wouldn't say he has any reoccurring dreams but there is always a sort of mechanical aspect to his dreams. Not steampunk but some sort of gears and machinery present in most of his dreams.
