aww that's so cute! My dutch bunny loves to nudge me with his head when I lay on the floor. I always crawl up to my bunnies and stick my face up close to theirs cause they like it when you get down to eye level with them, and Matt will nudge my forehead with his nose. My dwarf bunny lets me groom him, and sometimes when he's calm enough after lots of running around, I can just nuzzle my face into his back in that really soft spot behind their ears and he lays still and maybe thinks I'm grooming him. If I throw my head around and let my hair fly all over, Matt sometimes flicks his head back at me and throws his toys at me like he wants to play.
