It was around 7 pm when a light pungent smell hit the lower ground of my flat. We ignored the smell until the clock hit midnight then the pungent smell became so gagging. We off the tv & the lights. I place my daughter who was less than a year old nearest to the balcony (so very silly of me). I was in the middle and my hubby on my left. There’s no more pungent smell either but immediately after the light was off, come this eerie sinister sounds of laughter so loud, echoing into my ears. I caught hold of my hubby’s hand & yes, he was frozen with fear.
