Wet dreams, however many, are fine. The male body, left unabused by P and MO, knows how and when it needs to take care of itself with nocturnal release. The body naturally dispenses with old semen/sperm in other ways, too: precum, release in urine, breakdown and reabsorption back into the body. Retained sperm/semen never really stays retained forever - you'd explode if it did. There's is always constant release and rejuvenation, even without sex or MO. Also, no dream is ever a negative thing, healthwise. Even nightmares are the brain's process of filing and rewiring heavy data. All dreams, even sexual ones, are good; many sexual dreams have nothing to do with actual sex even, but what we're using sex or addiction for, to coverup and anesthetize our inner wounds, or a need for intimacy, communication, or loving connectedness. The unconscious mind knows this. Never suppress or try to avoid what nature does well (sex dreams, wet or dry), you'll only cause neuroticism to come out elsewhere, and possibly even fuel the greater need for addictions all the more. Also, don't necessarily buy into all the bullshit of semen retention - it is ignorant when it comes to male biology and natural physiological functioning as it should be (like natural release avenues). Also, while there are benefits, some of the acclaimed superpowers are overexaggerated and just plain nonsense. Proceed to let you brain rewire with clean living and let your body find its natural balance. That's what you need for recovery, as I have been finding on hardmode no-PMO for 170 days now. Best wishes!
