In The Shining, there is a backstory of how Jack decided to go sober. While in the car with his friend Al Shockley, both drunk, they hit a bike. But they cannot find the person they hit. Terrified by the incident, Jack realizes he must stop drinking alcohol.
What may be the meaning of this story? I think it was a message for Jack to stop drinking before something bad happens.
But still, I am not sure if I missed something. Was there any biker hit? Was it a ghost bike? Was it just their drunken imagination?
