This happened around a decade ago when I was in high school. In relation to my last story (Pitik) this has something to do with the backyard but it didn't happen in the same room but the other room where my mom is taking now.
I just finished doing laundry (I'm the family clothes washer, ha-ha) and the next day I folded them. That day my mom and my two siblings were away and I was alone in the house watching TV while folding the clothes. After I finished putting the clothes away, I went to my mom's room to put hers. When I opened the cabinet I heard a growl from outside the window. I thought it was an animal so I faced the window and the growling stopped. I simply ignored it at first and when I was facing the cabinet again the growl continued louder than before. I couldn't make up what animal was making the sound. It sounded really scary like a wild animal and a human growling combined, I can't describe it. Again I faced the window and it stopped. I was nervous to face the cabinet thinking I might hear it again but I still did it. I heard the growling much louder than the last one. The sound it made was too scary it felt so malevolent that it might do harm to someone. To my surprise I hastily put mom's clothes and left the room and closed the door. I never told anyone what happened.
Two months ago my Aunt Debbie had some problems with her boyfriend and she lived with us for a while. She and my mom were talking about something and it caught my attention. "Alam mo ba may times na nakakarinig ako ng angil ng hayop dyan sa likod? Kaya lang di ko mawari kung anong hayop 'yun (At times I can hear a growl in the backyard. But I can't think of an animal that is making the sound.) ". Hearing that sent chills down my spine.
