Alarmingly loud thunder at 2am MIGHT have started house fire and damaged town pool (closed it down this weekend) in Pleasantville NY.
Prior homeowner, costume designer, moved out 8 months ago.
FB comments refer to that "attic studio for PHS (Pleasantville high school), historic hudson valley and ARC stages"
Arc Stages – theatre for every stage theatre programs for K-12
https://hudsonvalley.org/
http://arcstages.org/
ARC also refers to: https://thearc.org/ (promoting and protecting the human rights of people with intellectual and developmental disabilities and actively supporting their full inclusion and participation in the community throughout their lifetimes) which appears to be unrelated.
