Oh no! Please don't! Although incubation of nightmares is a way to have LD but it will exhaust you mentally! Once I tried it for one week and after each nightmare I was so depressed and sick that I wanted to swallow out! These dreams were mainly about the sudden death of my beloved ones or white head corpses! I even feel sick when I remember them now!
Having LD in cost of damaging the mental health is not a good idea! So be careful please!
