Cat suddenly became annoying.

I love my kitty. We’ve had him about 2 or 3 years now. The past few weeks or so, he’s been waking us up by meowing, walking across our heads/pillows and other goofy cat activities.. we thought maybe it was because he wanted food or his litter box needed cleaning, so we’ve been doing pretty good about making sure those are always taken care of. I just don’t know what he wants!! He’s never really done this before. Anyone have any ideas?
