Actually it has nothing to do with dreams or urges.
Recent research suggests it is a natural healing process that goes on during sleep to revitalize reproductive organs.
In females, they say it happens with the clitoris.

"Morning erections are a normal part of male physiology. In fact, when doctors are trying to determine whether or not a man's erectile dysfunction is physiological or psychological, they will often apply a nocturnal tumescence monitor, which monitors the presence and duration of erections during the night. Several things can cause morning erections. One, as the bladder fills during the night, it tends to trigger a spinal reflex that can cause erection. Also, the congestion caused by the full bladder can decrease the outflow of blood from the penis. There are aspects of normal sleep cycling that tend to induce erection as well.
Erections are mostly controlled by the autonomic nervous system. The parasympathetic part functions during relaxed states. Erections actually occur when men are in relaxed states (you don't need blood going to your penis when you are running from a lion) and early morning is simply one of the most relaxed states."

Two things, because they probably have to pee. Secondly - when you're sleeping in one position for hours at a time, parts of your body get stiff... for instance, I have a hard time moving my legs in the morning 'cause of stiffness... hence, a stiff penis

Pressure of the full bladder constricting the penile blood vessels.
