Everything Is Real
Technically, anything that can be percieved in one's mind is real. It just happens to not be real in the way someone expects - it is there, but encoded in a different way. This means it is not a object made out of atoms, but something else, like the configuation of cells or bits on computational storage that rembember something.
There is also the phenomenon where something that is deemed "not real" is realer than something that "is real". For example, you could be talking to someone on the internet who "is real", but Hatsune Miku, who is "not real", can appear at a concert or in VR and appear more real.
