I also used to hear hissing sounds and some unusual pluck… pluck… pluck noise from my parent’s bedroom during night time, but I could not see wh...t they did. So this time I decided to steal a show of my sister’s bed room!I was impatient for the nightfall. In the night, after making sure that my mom and brother are fast asleep, I tip toed to my sister’s bed room, to peep through the key hole.
