how to make a jumpscare screen?

[Radical Batz]

Now I don't know how to do this but I would like to know how!

In my custom story, when the player opens this door I want the screen to squeeze in and a soundtrack will play and I want the player to gasp, how do I do that?

it's similar to the part where you open the last door at the sewer in the original amnesia game and you'll find grunt body parts, you know what I mean? What's the whole code of that pls
