что на острове 1 человек, который борется сам с собой, со своими страхами и совестью

Hey. I have a different take on the movie. Maybe someone will agree.

Two men arrive at an island to work in a lighthouse. Thomas Wake (William Dafoe) is older, knows better, is very jealous about the lighthouse and boss the other one around. Thomas Howard (Robert Pattinson), the other one, works hard during the day, has sexual fantasys with mermaids and keeps a dirty secret about his past. He may have killed his coworker, or his father, or maybe he just watched him die and took his name. Anyways, he´s ashamed about what happened: ""I ain't the kind to look back what's behind him, see? Ain't nothin' wrong with a man startin' fresh, startin' new".

After Howard kills -¿a seagull? ¿the soul of a sailer? - the wind changes, a storm comes and they cannot escape the island anymore. Time passes, no one knows how much, and Howard descends to madness until he kills his partner, touches the lighhouse and dies. Then he gets eaten by seagulls. ¿What just happened? ¿What is it all about? Here is my take on it.

Thomas Wake is actually Thomas Howard´s subconscious. That is why Howard works the day and Wake the night. They take shifts over the same body and they only see each other when they go to sleep or when they awake, a time were our inner world interacts the most with our consciousness. They also can talk freely if they are drunk. That explains why Wake knows everything Howard does and did in the past, keeps notes of his behavier and is awful critical about his work performance. Still Howard has to obey him, as we usually do what our subconscious dictate: "Well, you ain't a captain of no ship and you never was, you ain't no general, no copper, you ain't the president, and you ain't my father -- and I'm sick of you actin' like you is! And I'm sick of yer smell. I'm sick of it, you goddamned drunk". This is Howard actually hating himself.

¿Why? Because he did something he regrets in the past and is seeking solitude and peace in this lighthouse. But when he kills the seagull the storm comes, he starts to confront his subconscious to the point of madness. He desperate needs to know what is hidden the lighthouse, the thing that Wake sees everynight smiling. Even Howard doesn´t know for sure what he did, his own hidden truth. Wake knows.

The mermaid´s mythology indicate that they sing until sailmen fall in love, lose their minds and drown. This is the temptation of Howard to seek the horrible truth, and when he buries his subconscious he can get to it, be burned by his own guilt and comit suicide falling down the stairs. He is finally naked and eaten by the souls of the people he killed. By his own guilt.

At the begining the two men arrive at the lighthouse each carrying their own baggage and two men are leaving from it, carrying the baggage between them. That is after they become conscious of their hidden truth.
