Baby putting hands in mouth

I’m a FTM to a 10 week old. For about the past week in the middle of the night she’s been trying to put her hand in her mouth while sleeping and making SO much noise. She wears a love to dream swaddle so she can’t actually get her hand in her mouth. Her eyes stay closed so I assume she’s still asleep. When I try to put her pacifier in she will spit it out and go for her hand again.

What do I do in this situation? Do I just leave her be? She is not crying and does not seem distressed. I have been getting her to change her diaper and give her a bottle but when she falls back asleep and I put her back down her starts with the hands again
