“When the pupil is ready, the teacher will appear."

Dick tells Danny that even though he was his teacher regarding his abilities, Danny is also going to be someone’s teacher. Someone is going to need Danny’s help, and that is when that person will appear to him. The quote foreshadows Dan’s relationship with Abra, as well as the effects that Casey, John, and others will have on Dan.

“Maybe you can put the things from the Overlook away in lockboxes, but not memories. Never those. They’re the real ghosts.”

When Dan sees the bruises on Tommy’s body, he wishes he could lock away his memories of Wilmington. Dick’s voice, in his memory, reminds him that memories can be harder to deal with than ghosts. Memories haunt Dan in a way that make them impossible to banish, unlike the spirits from the Overlook. And memories that are repressed for too long began to eat at their hosts from within.

“There came a time when you realized that moving on was pointless. That you took yourself with you wherever you went.”

Since his time at the Overlook, Dan has avoided mountains. However, now he realizes his torment lives within his memories and within his preternatural gifts. Until he makes peace with who he is, he will never be able to outrun his past.
