Forum:Tcg rulings of field barrier

alright, here is my situation. i currently dont have a field spell card on the field, can i activate field barrier even though i dont have a field card to prevent my opponent from activating a field spell card (i.e. zombie world). i think you can but my friend dosent, we looked it up and didnt find anything to support either side. we are at a stale mate... what do you guys think?
