Your Prayer Plant needs bright indirect light, high humidity and to be kept moist but not soggy. If it is developing dry spots and the new leaves shivel, its either too much or too little water.
If it is dry in the top half inch of soil, I would say too dry. If the soil feels water logged, too wet. Also, they hate dry air so if an air duct is blowing on it, the plant will not be happy.
If you decide to repot, use something like violet potting mix and plant it in a pot that is shallow and wide.
They are kind of touchy plants but when you manage to address all concerns, they are beautiful.
