What does it mean if he kissed my cheek while I was sleeping?

I was "sleeping" next to him and in the middle of the night he woke up and quickly planted two kisses on my cheek out of nowhere and went straight back to sleep again, face to face really close to me. He did it one time before as well when I fell asleep in his lap. We're not together, he is not my boyfriend, he is a guy I'm seeing and I like him a lot.. Hopefully he likes me too?
