The living room light, is it a lamp plugged into a wall receptacle or a ceiling fixture? Answer this question and then I will have more questions eventually leading to a suggestion about the problem you describe.

Both are ceiling fixtures on separate switches.

you have a loose neutral

Are you saying that if the living room light is off and you turn on the closet light, the living room light comes on dimly?

yes

Its a MWBC (Edison) and you have a loose neutral.

From the beginning, I have considered that this may be a serious post and that the described problem actually exists. But also considered that maybe it is not.
One responding post suggests a loose neutral. And the system at that premises may have that problem.
But the poster says that with the living room ceiling light OFF (switch OPEN), turning on the closet light makes the living room light glow dimly. Lets say there is a loose neutral and turning on the closet light supplies some voltage to the living room light via the neutral (white). But the other conductor (black) connected to the living room light is connected only to a switch which is OFF. So how does current, of any amount, flow through the lamp (bulb)? And no description is given about how the closet light presents in this instance.
Perhaps this post was just a spoof.
