I want to know the answer to the following question:
Who ran from house to house, laughing, screaming, and singing?
All the background I'm provided with is that "The Strumica Carnival (Macedonian: Струмички Карневал, translated Strumichki Karneval) has been held since at least 1670, when the Turkish author Evlija Chelebija wrote while staying there, "I came into a town located in the foothills of a high hillock and what I saw that night was masked people running house–to–house, with laughter, scream and song.". Is that enough to answer the question?
Answer: yes
