No. It is not normal at all. Go to a mechanic and get their opinion. Engine knocks usually signify severe damage, and driving with it will cause even more damage. Always check your oil as well. Make sure it is clean and topped off. knocking can also sometimes mean you have the wrong octane but most of the time it means your tie rods or connecting rods are worn

A knock at idle however can only be bearings, it would be beneficial to get things looked at right away,
