Deep sleep

I feel bad I was extremely tired last night so my mom got my one month old like at 3 in the morning she brought her back to me at 7 and I woke up and looked over she was in my arm I don’t remember my mom bringing her to me or me laying her down . I guess I was still sleep . My mom said I was talking to her and everything and I just don’t remember...also before she came in my room she heard me talking loud . I guess I was sleep talking . Anybody experienced this?
