JavaFX how to add long text to GridPane - Wrap in ScrollPane ? How?

Question

I'd like to add long text to my app. When I click POKAŻ button it shows me my dream fields(String) from class called Dream. Here I have a problem. The content of my dream is very long and it is not completely displayed. When i wrap it inside a ScrollPane it shows me only one line of text.

Here is a printscreen of my app.

I might add that after I clicked POKAŻ button it changes the .fxml file

        public void showMeMyDream(ActionEvent e) throws IOException
    {
 showSelectedDream();
contentID.getChildren().clear();  contentID.getChildren().add(FXMLLoader.load(getClass().getResource("/fxml/showDreamFXML.fxml")));

    }

Here is the code of showDreamFXML.fxml

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.geometry.*?>
<?import javafx.scene.text.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.VBox?>
