What does the ghost mean when he says to Brutus Thou shalt see you at Philippi?

In Shakespeare's 'Julius Caesar', the ghost of Caesar appears to Brutus before the Battle of Philippi. He tells Brutus, "Thou shalt see me at Philippi." This has two meanings. First, it is a warning that Brutus will die at Philippi. In fact, Brutus does commit suicide at the end of the battle after realizing that his cause has been defeated.

Secondly, it could also be interpreted as an invitation from the ghost of Caesar to meet him in the afterlife at Philippi. The ghost of Caesar is clearly not happy with Brutus, and the prophecy could be seen as a threat or a warning. Either way, it is a foretelling of Brutus's downfall.
