Continuing to race, Luke didn't even hear anyone yelling - the only way he knew that the monstrosity he was running from did anything was from the intense heat that he felt emanating from behind him. This threw all caution to the wind - who cared if he risked hurting his legs, it sure as hell was better than being barbecued. 

Almost immediately, a small girl ran past the entire group, leaving Luke in bewilderment. How could she possible move that quickly? Luke had been running for years now, and participated in several marathons, and yet a small girl was easily beating him in a foot race... This reminded Luke that this was obviously a dream, and he really didn't need to take it so seriously. He just ate something spoiled, or was having a fever dream, nothing more. 

As the others continued to run alongside him, Luke simply ignored their screams - they were all saying the same things, and he was too busy wondering why the hell this dream felt so real - no other dream in his life had such realistic feelings and sensations. Still, the only thing he especially cared about was waking up as soon as possible, since it had stopped being entertaining once the large man entered the scene.

At a considerably easier pace, Luke began to follow the stranger - something he only did simply because he thought it was his mind telling him how to wake up faster.
