hearing voices

ok i know this is going to be really weird and probably scary...it wasnt even halloween, it is freaking christmas for ghost story...

i have this weird encounter and it actually happened for quite a handful times but most of the times, i just ignored it. but not for this most recent incident and it happened twice. MOST important part, i am not alone.

on the 22nd i take leave and went back hometown to have reunion dinner with my family and while on it, take a break off the stress. and while enjoying my day at home, i was playing with my niece with my 2nd sister watching. and i suddenly heard my mom called me. so i went over to the window (she is at outside) and asked her why she called me. to my surprise, she said she didnt call me. obviously i wasnt happy with that answer because i DID heard her calling and i argued with her that she DID called my name. and she said she DIDNT call for me. trying to push it aside with the thought i probably heard it wrongly but my sister suddenly said she heard someone calling me too..

freaky right...fret not, thats not the first time. the other time, she also heard someone called my name and the same answer from my mom (i heard she called me) but apparently she DID NOT..

so i went and google-ed it. yes, you can try google "hearing voice calling name" or anything similar and voila, you will get a freaky answer. but let me point out the difference here.

1. i heard my MOM called me, meaning i can identify her voice instead of a random person calling like those on google's claimed.

2. i have my sister hearing the same thing like i did. those on google heard it in their ears alone and so they think they are crazy. (but then it happened to me also, when i was small)

and so i still doesnt get an answer that convinced me..
