From what I gathered from the 2 different owners, they heard laughters and sometime cries in the middle of the night. I told them they might have heard wrongly, as there were many cats around my place. And when cats are in heat, their calls can sound un-nerving, just like baby crying. But then cats don't laugh.
The 1st owner had 2 young kids, and the 2 kids will cry non-stop when they hear the cries. So after 2yrs, they sold the place and moved.
The 2nd owner spent 1 year rebuilding the house, moved in for a year before selling it. He was a contractor, so he probably did it to make money.
3rd owner was super sombong, not even a hi or bye. Stayed for less than 2 yrs.
4th owner was a young family. A couple with a cute baby. Stayed for about 1 Yr. He said he can't take it anymore. His baby kept having nightmares will scream and refused to sleep when it's bedtime. But he is OK when he is at the grandparents place.
