Just recently my horse has been acting a bit weird when I ride him. He is grabbing the bit, sticking his head way in the air, and then running really fast. He'll do this suddenly, then come back and go normally for a while, and then he'll do it again. He also shakes his head periodically. He has never been super steady in the contact but this is above and beyond normal for him. I am not sure what to do or why he is doing this.
Yes, push forward...but also make sure you keep your hands down and steady, and be quick to reward when he does come soft and round. It likely your hands are the problem rather than him tossing his head
