Horror movie name ASAP plz?

Hello, I’m looking for a movie, but I actually don’t remember much, but, here’s what I know:

  • before 2015

  • The characters are from a wealthy family

  • it starts with a scene of them going to their mansion in a black car, and on their way, they face a Herd of ibex (the ibex are within the mansion boundaries), and one ibex looks the boy in the eyes.

  • There is also a scene where the boy hides in the bathroom, but then a green light glows out of the toilet.

  • The movie quality is high

  • The movie was filmed in the same area where the King of Spain has a mansion.

Thank you in advance.
