This experience took place back in 2014 I believe, when I lived in Portugal with my ex-boyfriend.
It was night-time and me and my ex were watching a thriller/paranormal movie. The volume was pretty high, to make ourselves more scared.
I think we were past half way through the the movie when we suddenly hear something through the loud sounds from the TV. What we heard was "ahhhhhhhhhh". It was not a scream, it was more like when you got to the doctor and he wants to check your throat and you have to go "ahhhh". And it was coming from a woman.
We knew right there and then it was not coming from the movie, because the scene it was showing didn't have any females in it, and it was coming from outside the bedroom.
My ex turned down the volume, so did the voice. The voice was actually lowering at the same speed as the sound of the movie. (Once again, the voice is not coming from the movie)
We get off the bed and open the bedroom door. That's when we hear the family dog...she's growling. She only growls when she feels threatened or if something is very wrong. We even went outside, but nothing, it was completely quiet. That's when my ex suddenly says that the voice came from the second floor. We looked at the dark staircase leading up to the second floor.
We knew nobody was up there, cause we were all alone in the house.
The family dog didn't stop growling for maybe ten minutes.
When we went to bed later on, I could have sworn that I had heard a scratching noise from outside... On our window.
