No, you should not believe everything you read or hear literally. Common phrases like "it's raining cats and dogs" and "it cost an arm and a leg" are idioms that use exaggeration to make a point and should not be taken word for word. Idioms like "hit the books" and "under the weather" are phrases where the meaning is different than the literal definition of the individual words. It is important to understand idioms in context rather than believing everything at face value.
