This story takes a place in a house standing in the middle of field.
I assume this is in a conflict of person vs himself.
Climax of this video is when Stanley finally buried his parent's dead bodies and set himself free.
The dead bird the misterious girl had in her hand was black and symbolizing something ominous. It could be heralding the terror she would experience by Stanley's weird act.
Irony in this story is his parents are in fact not real human anymore but just machine he created so that he won't be alone.
I figured out this theme of the video is, "It is better to live a real life alone than livening surrounded by fake people "
