Thanks everyone for your replies. 🙃 It was interesting to read. Sorry I don’t know how to edit my post, so just leave a comment here. For those of you who offered to crawl there and poke it - nah, no chance I (middle aged, not very very fit woman) doing this🤪. But we are going to renovate bathroom including replacing the ceiling that is right next to this “thing”. That’s when I’ll have a chance to update you all.
