I don't get it: I actually undressed myself (însumi!) under a bridge before bathing in a small river because I didn't want to get naked in front of everybody, and because there was less wind, and a concrete patch to keep my clothes clean.
Why is this loco? Many situations can occur in life other then asking directions for the central station...
In English we more often say "We get undressed ..." or "We undress ourselves ..." than "We undress ..." though we would say "We strip off ..." without the "ourselves"
I'm thinking it makes no sense to say sub pod with the attic sense. I'm sure there are other ways of indicating your location other than this way.
