The soliloquy serves to convey Brutus's thoughts and motivations to the audience.
Fear that Creon is trying to take his power and crown as King as Thebes
Brutus was among a group of Roman senators that believed Julius Caesar had too much power. Brutus felt that any hope of returning Rome back into some form of a republic would be lost if Caesar was allowed to continue on the path he was following. Brutus believed that Julius Caesar wanted to become the king of the Roman empire. Brutus became a secret enemy of Caesar. He certainly had fear of his own life as Caesar had dictatorial powers and could use them against any internal Roman foe. Based on this Brutus conspired to assassinate Julius Caesar. The deed was accomplished in the Senate chambers and Brutus was among those who stabbed Caesar to death, thus the tragedy of Caesar and the lament of Caesar's friends.
When the crowds are shouting Brutus fears that they are asking Caesar to be the king. Cassius is trying to persuade Brutus to help him kill Caesar.

What does Brutus fear?
Angrophobia is the fear or anger, and Acousticophobia is the fear or sound. Both of these phobias can be specific to shouting.
Brutus presents himself as nonchalant, unbarred, and unfearful of the voice he hears till he realizes it was the real ghost of Caesar & is stricken with fear, fear that predictably roots from guilt & commands Cassius to gather their troops & go on their way.

Unfortunately not. Brutus thought that without the support of Caesar, Antony would be of no significance. He failed to realize the threat that Antony posed.
Cassius convinces Brutus to join the plot to assassinate Julius Caesar by appealing to Brutus's sense of honor and patriotism and by highlighting Caesar's growing power and ambition. Cassius also plays on Brutus's fear that Caesar's power will diminish the Roman Republic.
