The answer to this question is yes.
The only internal one I ever learned was character versus self.
The others are external:
Character versus fate
Character versus nature

Character versus society
Why would everyone be concerned about Anne's nightmare?
D. Because they do not want to be discovered.
The reaction the others have is to silence Anne because her screams “are endangering all our lives”, as Dussel comments. Mr. Frank as well was alerted by the sound and tries to calm down Anne, he wants her to “lie quietly”.
