Illusory

Alex rubbed his head a little and carefully looked ahead. He could still clearly see the end of the path, but he had just hit something. 

He slowly extended his arm forward until his arm touched something. "A barrier?" he wondered and felt it a little more. The more he felt it, however, the surer he was that this was not a barrier.

He closed his eyes and tried to understand what he was feeling. "This feels like the walls of the maze," he thought as he felt the tiny leaves and branches. 

He suddenly backed up and looked at the whole thing again. Only this time, he used his Spiritual sense. 

"There truly is a wall," he thought as he saw the wall finally. To the right of him was an opening. He opened his eyes and looked at the opening. He could see a wall there. 

He slowly moved to the right while extending his arms like a blind man finding his path. Soon he reached the wall and tried to touch it, but there was nothing there.
