Should I worry??

I just woke up half an hour ago. But I was hearing voices. I wasnt asleep. I just had my eyes closed. I was almost asleep. I could hear a voice like my mothers. But softer and nicer. "Im here" she said. But then I could hear a little girl. She sounded closer. She giggled and said "here I am" she kept gigling. I wanted to see the girl so I opened my eyes. She had brownish blonde hair tied up. And she was wearing something yellow. I closed my eyes and then opened them again and she was gone.... I dont know what to think anymore. Im always experiencing something like this one way or another
