On the day Will and I came and finished patching the roof leaks, it happened to rain a few minutes during the repair. We took the opportunity to walk through the house and inspect the major leak spots. We discovered that we had not yet stopped all the leaks, though the majority of them were slowed down. Maybe the tar had not set enough yet, and the leaks would be stopped shortly after the sun came out.
Still, we hunted for vessels to catch the rain, and avoid as much damage to the walls and floors as possible. 
I removed the dresses from the worst part of the too-alive closet, and placed cooking pots under the leaks. It was a very uncomfortable job, as I could feel the dark presence sidling along the back of the closet the whole time, and there is little that is more distasteful to me than the rotten-colored streaks in water-damaged plaster. The streaks are too much like spiritual gloom.
I placed the poor, stiff dresses on the bed frame at the other side of the room, and turned to inspect the closet and leaks.

The closet had changed. Yes, more natural light was able to get in, but this was not the difference. It was a different sort of brightness. Much of the gloom had gone.
In its place was the beginnings of peace, and restoration.
Was the presence then attached to the clothes? I don’t know. There didn’t seem anything particularly sinister about them as I handled them, or as they lay on the bed.
Yet, the closet was spiritually cleaner.
Any ideas?

I know the terminology borrows a bit from eastern philosophy, but you might be dealing with strong psychic signatures interacting with one another. Kind of like yen repelling yen or the positive side of a magnet repelling another positive.
I know only what you’ve told me about the house’s occupants, but it’s possible for two people to have conflicting personalities or perhaps a past of some kind. By themselves, there’s nothing sinister or problematic, but together, they clash and fight. Maybe their possessions are still doing the same thing even after the owners are gone.
That’s entirely possible, John. There are still energies, spirits, or something (I’m not entirely sure what yet) hanging about in that closet. It’s just that the great, repelling blackness is gone.
I solved part of the mystery several days after writing this post, and Scooby Doo didn’t even help!
I’ve yet to put this post up (it’s half-written), but I did some spiritual clean-out in the pantry, which is just across the wall from this closet. In there, I found mega darknesses, of several varieties, and – I had to laugh at my simplicity when I recognized this – one of them was the being from the clothes closet. He’d just bounced through the wall and found somewhere else to hide as I took the dresses down.
