“But a stranger in a strange land, he is no one; men know him not—and to know not is to care not for. I am content if I am like the rest, so that no man stops if he see me, or pause in his speaking if he hear my words, to say, “Ha, ha! a stranger!” 

Dracula foreshadows his plans to move to London and some of his motivations for learning English so well. He wants to be able to blend in, so that no one can mistake him for a stranger. His eventual crimes would cast suspicion on outsiders or newcomers first, and he wants to remove that possibility.

“There is a reason why all things are as they are.”

Dracula tells Jonathan not to try the locked doors in the castle, but his statement foreshadows his ability to plan meticulously. Dracula’s move to London requires great resources, coordination, and audacity. He believes in the predestination of his own success, and will model his takeover of London similarly to the control he exerts over his castle.

“Despair has its own calms.” 

Jonathan sleeps after the Count tells him to make the letters. He is beginning to accept his fate; he is trapped. He counts on his dreams to find peace. This foreshadows the importance of dreams to other characters, later in the novel. Their dreams are nightmarish, and they often confuse dreams with reality.
