Solution to "A Wind Blown from Paradise" by N.C. Hunter Hayden

DWELL ON or TURN AWAY FROM each of the three memory triggers: the poster in the starting room, the ad on the train, and the magazine in the waiting room off of another station.  Each time you DWELL, you will be taken (in memory) to the beach.  You will leave the beach after a set number of turns.

Then the train will take you to the station with the map of the subway.  If you have dwelt upon enough of the triggers, you will see on the map only the name of the location of the beach.  DWELL ON the NAME and you will enter the beach a final, brief time, before returning to the station, where you will BOARD the train and the game will end.

If you have turned away from all of the triggers, you will see on the map only the exit location from the station you are currently in.  LOOK at the EXIT and go UP to the street, and the game will end.

If you have a certain combination of dwellings and turning away froms, you will see both the EXIT and the NAME on the map, and you will have a choice of which ending to select.

To ride the train: BOARD TRAIN, or GET ON TRAIN, or just BOARD or GET ON.  Other commands are recognized as well.  There are several different stations.  If the train does not take you to your desired destination, simply ride it again.

To get in and out of the waiting room: ENTER ROOM, OPEN DOOR, ENTER WAITING ROOM, EXIT ROOM, EXIT WAITING ROOM.  Other commands are recognized.

Every time you dwell on or turn away from a trigger, your perception changes.  Every time you return to the beach, your memory is less specific.
