As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
There are many young people that are growing up and may have heard the term wet dream, but do not know what a wet dream really is.
 
In principle a wet dream is when an adult has a dream of a sensational nature in which fluid is spontaneously ejaculated from the private part of a male and he wakes up and find wetness around his private parts on his garment. In the case of a woman the front private part will become moist. The wetness could be in the form of mani (semen) or mazi (a pre-coital fluid) or wadi which  is a liquid that precedes the urine. (Bahishti Zewar vol.1 pg. 72)
 
There are fourteen different scenarios in relative to the issue of wet dreams.
 
If one wakes up and experiences wetness around  his private parts or clothing or his undergarments then he will have to make Ghusl in the following situations:
 
1)     If he is convinced that it is semen and he remembers  having a dream 
2)     He is convinced that it is semen even though he does not recall having a dream 
3)     He is convinced that it is pre-coital fluid (mazi)and he remembers having a dream 
4)     He is uncertain if it is semen or pre-coital fluid but he remembers having a dream 
5)     He is not certain if it is semen or wadi (the fluid that precedes urine), but he remembers having a dream 
6)     He is not certain if it is mazi (pre-coital fluid) or wadi ( fluid that precedes urine), but he remembers having a dream 
7)     He is not sure which of the three it is (mani, mazi or wadi) but he remembers having a  dream 
8)     He is not certain whether it is mani or mazi, nor does he remembers having a dream.
 
9)     He is convinced that it is mazi, but does not remember having a dream.
10)He is having doubts whether it is semen or wadi, but does not remember having a dream.
11)He is uncertain whether it is mani, wazi or wadi, but  he does not remember having a  dream.
 
Ghusl will NOT compulsory upon him under the following circumstances:
 
1)     He is having doubts whether it is mazi or wadi and he does not remember having a dream
2)     He is convinced that it is wadi, but he does remember having a dream.
3)     He is convinced that it is wadi, but he does not remember having a dream. (Bahishti Zewar Vol. 1 Pg. 72-73)
