Dark ghosting/splotches showing up in render...

HEYO!

I am hoping somebody might be able to help me with an issue I’ve been having. Have tried everything I can think of. Basically, I’m getting some weird “dark ghosting/popping” around objects in my renders and can’t figure out WHAT is going on. Below is an image of the areas where it’s happening. It happens around 3/4 in on the middle area and at the end on the left area.

Would appreciate any help!! Link to video is below!

Thanks!
