Answer:
Brutus questions if he is seeing things when he meets Caesar’s ghost.
Step-by-step explanation:
An internal conflict is one that happens inside one's mind. It is about considering consequences, rethinking decisions, having trouble to identify the morally correct thing to do and so on. In this case, it doesn't matter if Brutus saw a ghost or not. What matters is that the conflict is of him trying to be sure of if it was a ghost or his imagination. This part is the internal conflict.
