This is lovely! & I think the title works well, although I think you could even shorten it to "From the Other Side" and omit the word Nightmare and still get the same effect. Also, I find this more much haunting than Nightmarish, personally. Regardless, this is a lovely photo!
Oh thank you. I agree that "haunting" might be a good word for it. And yes, at first I had named it just " From the other side" but.. i found it.. idk like evryone's done it before? That's why the nightmare.
