Why is my light acting this way?

I am trying to set up a scene where I have a character wake up in the middle of the night and I have a stream of moonlight coming in to light the room.
Now in my scene I have a spotlight, directional light, and atmospheric fog.

The first issue I need to address is why I am getting so much bounce inside of the window rather than around the room

I honestly have no idea where to go from here. Please help

It’s not the bounce light that’s intense, it’s the actual direct light that’s intense. Your directional light intensity is set to 20. Lower the intensity to 1-5 range at least, and let light adaption do its work.

It seems like a thick window, combined with the direction of the lightsource that is causing it to look like that.
