possible hearing of a mimic?

i 21F (hispanic) am and was raised extremely christian, was made aware that there are spirits and that they are around and it is something that you should never call too no matter what.

i choose to live by that especially involving witches and witchcraft, as one of my ancestors made the wrong choice when coming across one.

furthermore, being christian, i still find the paranormal interesting and am very aware. there's been an ongoing thing of my family members hearing a very specific person calling out their name yet the person is nowhere to be found. i was told that it was spooky, but we never dove into it any further.

this past week i had gotten home from a horrible day at work, i showered immediately and began blow drying my hair in my bathroom. while doing so i heard a VERY distinct calling of my name that i assumed was my mother, to make sure i didn't hear it by mistake i quickly shut off the blow dryer to see if she'd call out again.

my name was called out again, i believed it to be my mother and in the tone my name was said, it was one of those "well i must be in trouble" tones. i set down the blowdryer and opened my bedroom door and called out a "yes?".

nothing... absolute silence. i shrug it off and assume i took too long to respond so she must've left. i grab my phone and dial my mom's number, she answers and i immediately ask "did you need anything? i heard you calling my name", she goes silent and says "i'm not even home, your grandparents and i are running some errands"

i freaked out and explained everything and how i swear i heard her calling my name with urgency. she then says "nobody is home besides you". my mom started freaking out with me, said "mom it was your voice exactly, it sounded like you were angry with me"

so now we're both scared and confused. my mom had the exact same experience years ago when she swore she heard my grandmother (her mother) knocking and calling for her at the door, and similar to this time, nobody was there. and my grandma was at her own home.

opinions or a possible debunk of this situation?
