What technique did warhol use to reproduce images?

This isn't school related, but i need , i'm typing a story and i want to open with an omniscient limited point of view, where a woman with ptsd is dreaming and the reader doesn't know it's a dream yet. you even have to give me an opening sentence, but an example from a book with an omniscient limited point of view would alot. if you don't know what i'm referring to. "definition of third person limited. in third person limited the narrator only knows the thoughts and feelings of one character. all characters are described using pronouns, such as 'they', 'he', and 'she'. but, one character is closely followed throughout the story, and it is typically a main character."

This is just a little thing i just did for fun! hope you enjoy! a: ~what would you first grand if your house was onfire? b: ~what do you first notice on a person? c: ~ what are some challenges you think the next generation will face? d: ~what is the most embarrassing moment in life? e: ~what is your favorite artists? //music//f: ~what are some bad habits you can't stop doing? , but you know you need to stop on them.i really hope you had fun doing this, or not doesn't matter, but if you want more from me contact me! bye now//i can't wait to see some results//ㅋㅋㅋㅋㅋ나를 따라라! ^^(i'm going to put this under arts, even though it's not, so yeah)
