About the naked guys:
I, personally, hate them. I think that it's a very cheap, bad, overused and crappy jumpscare. If I'm in a story and I suddenly see one of these, I give it a margin of another one to quit (how ironic, my first story had those too... how much do I regret that story)
Anyways, welcome to the forum! Don't mind making more help threads, everyone needs help at some point, and we'll be glad to help you
About your problem:
As Harry Potter said, there's a magnet icon: I'm pretty sure you'll have noticed that when you drag around an object, it moves along a grid. If you toggle off the magnet, it won't snap (be careful though, it's very hard to make things match if you don't use the grid, use this only to put some things, but never use it for structures!)
With that said:
Put the flying guy in a manner that it's floating inside the cabinet, and that it doesn't touch anything. I'm pretty sure that'll fix it.
I don't reccomend disabling collision for the cabinet, you can always resize the cabinet just a bit (the necessary space for the man).
