It depends. Sometimes works labeled as 'Mea Culpa' are based on real events, but often they incorporate fictional elements or are entirely fictionalized.
Well, here's a Nui guy ghost story. The Nui guy was traveling alone at night. He passed by a cemetery. All of a sudden, he heard strange noises, like whispers. Then, a shadowy form started to emerge from behind a gravestone. It was a ghostly apparition. The Nui guy's heart started pounding. He tried to run, but his legs felt like they were stuck. The ghost slowly floated towards him, and he closed his eyes in fear. When he opened them again, the ghost was gone.
I'm not sure specifically which 'mea culpa true story' you're referring to. 'Mea culpa' is a Latin phrase meaning 'my fault'. It could be a personal account of someone admitting their mistake in various contexts like in a relationship, at work, or in a social situation.
Without more context, it's difficult to provide the full story of 'mea culpa' in the Philippines. It could potentially be related to a political scandal, a religious matter, or an individual's admission of guilt in a particular situation. For example, if it was in a political scenario, it might involve a politician taking responsibility for a failed policy or unethical behavior.
One common element could be a spooky location. For example, an old, dilapidated building or a desolate forest where the Nui guy might have his encounter with the ghost. Another element is the feeling of unease and fear that the Nui guy experiences. And often, there are strange noises or unexplained phenomena like cold drafts or objects moving on their own.
