Almost certainly just a funk if you haven't changed anything with your game. Every so often I go into similar little funks too, get out of it by going to stick and pucks and just really work on stick handling with your head up, shooting with your head up, and on receiving hard passes if possible. You've probably lost a bit of confidence for whatever reason, the best way to get it back is simply practice, get that muscle memory back to where it should be. And in games make sure you're not getting one step ahead of yourself, very often guys will start thinking about/getting into their next move while a pass is on the way, then bungle the pass reception, make sure you've got the puck where you want it before going into the next move. Once you're playing smoothly again you can get fancy and more instinctive, but for now keep it simple.
One other tip I can give is to wax your tape job, and melt the wax in with a heat gun or hair dryer. I do find my stick handling is crisper when my blade is snow/ice free, and properly waxing your blade can keep it basically snow free all game.
