Baby headbutting me while sleeping

My 2 month old sometimes sleeps on my chest before I put her in her bassinet.

While she’s sleeping on my chest, she’ll randomly at certain intervals pull her head back and then go back on my chest, all while sleeping. It’s kind of like a headbutt, but with her cheek that she’s sleeping on.

Anyone’s baby do this??

Idk if it’s between sleep cycles or she’s trying to get comfortable again or her face got hot. She’ll do it like 2-3 times and then stop.
