Brief Answer:
Nightfall is normal thing

Detailed Answer:
Hello,

Thanks for writing to us.

First of all clarification about night fall:

In all boys when puberty starts around age of 13 to 17, production of testosterone increased. This leads to increase in body hair, beard and moustache as well as production semen and physical body changes.

Semen is produced regularly after puberty by prostate and testicles and stored in seminal vesicles. This semen in general is expelled by masturbation or sex. When someone does not actively expel semen through masturbation or sex, there is excess semen in seminal vesicles.
When production rate exceeds capacity of storage of seminal vesicles stored semen has to come out to give space to newly produced semen.
This excess stored semen comes out during sleep, urination or defecation.
In sleep during dreams or excitement with slight force excess semen comes out and it is known as night fall.

If you are not doing masturbation regularly or not involved in sexual activities, night fall would be there. It is absolutely normal phenomenon and not a problem/disease.

If you actively try to expel the semen through masturbation/sex frequently, you would not have this nightfall.

In any case if you don't want to expel semen actively, you can use drug to prevent night fall. Clomipramine is the medicine used in treatment of premature ejaculation and it can prevent night fall. You can also do the kegel exercise.

Hope I have answered your query, I will be happy to help further.
