If we are unconscious while we sleep, how do we still react to certain things while sleeping?

So ive been wondering about this a while. I always wake up a fair bit before my GF wakes up. and i’ve noticed that even while she’s asleep she still responds to thing like me giving her a kiss on the cheek while she sleeps. and when I get out of bed she always IMMEDIATELY turns over to my side of the bed.

a quick google search tells me that no, we are not aware of our surroundings while sleeping. but i’ve seen a lot of things that seem to contradict that.

More than 90% of what your brain does are things you have no awareness of. While you sleep you still breathe. You only really have agency to allow for decisions within a complex mix of states (emotional, physical, environmental). Beyond that it’s not something you consciously are aware of.
