Same for me. It's like the feeling you get in a dream where things seem normal and you think you're awake, then suddenly you notice something wrong about the room, something impossible.

I know exactly what you mean. Like if you had to see it in real life you'd see something horrible just out of shot. For some reason that's amplified with the furniture.

Just wait until you can’t tell the difference and then contemplate if it matters, and then if that’s what reality already is.

Don't look at the food, I advise.

I get the same feeling, to the point that I occasionally let out a brief scream when browsing GAN images.
