One of the places where you need to start climbing

You will now have to play through another vision, where Garrett will have to follow Erin's voice. Interact with the poppies that you find along your way, reach the ledges located above and climb up to reach them, and open the door. The entire scene is very linear and you will have to use the lockpicks, at some point, on one of the drawings of Garrett's. Finally, approach the woman leaning against the wall.

wait until you regain control over your character and take the exit. Leaving the asylum ends the fifth chapter of the game.
