This seems like it could be a simple cipher or code. A common guess with short phrases like this is a (shift cipher).
Alternatively, could this be a puzzle where each word maps to a number? "hqyz snhyyty yph - -wnh 1" — the last part - -wnh 1 looks like --wnh 1 possibly meaning "minus minus wnh 1" ? hqyz snhyyty yph - -wnh 1
"hqyz snhyyty yph - -wnh 1"
