wet

Dear Respected brothers and sisters, Asalamualekum.I am only 18 years of age and this is the first time ive come accross this situation. Two nights ago, i dreamed of having Intercourse with a women i did not know, and today while sleeping i ejected semen. This is also known as a "Wet Dream" if i am correct.When i woke up to pray fajr i relised my cloths wernt clean. So i took a shower and prayed.Can you please enlighten me what islam says about these dreams and are these dreams from shaytaan?Thank You
