I heard my name whispered in my ear.

I was about 9-10 years old when I heared someone whispering my name in my ear. At that age I was always scared to sleep alone in my room. So i slept in my dads bed like i did most days. He snores but I got used to it since he's been doing it forever. One night i couldn't fall asleep, I heared someone whisper "Sara" in a deeper manly voice into my ear. I responded by saying "yes dad?" Fully convinced it was him. But he was fully asleep. Of course i was scared my heart sank no joke i still dont know what happend.
