Baby talking/playing in his sleep?

Shelly • Mama to 👦🏼 Jesse 6/4/19 & 👶🏻 Jameson 3/11/22

So my son usually wakes once in the night between 12am-2am to eat. I heard him and looked at my phone and it was 1am so I tapped my boyfriend (he was going to feed him) to tell him he’s awake. He was talking softly and making his ‘oughhh’ excited noise that he does and he was worming his way up his crib a couple of pushes. He also blew his bubbles once! My boyfriend looked at him then rubbed his eyes as he was getting ready to get up. I kept looking at my son though because he wasn’t picking his head up like he usually does? I told my boyfriend to wait a second and then he just stopped. He didn’t move or talk anymore he was just asleep like nothing happened! He was playing for a good minute/minute and a half though?! I’m not sure if he was awake and fell back asleep really quickly or was dreaming and playing in his sleep? Any similar experiences?
