TFNR - The Principle of Reality
In this model of description of Reality, everything is real. There is nothing out of Reality, nothing out of Nature, non-real, under-real or super-real, nothing supernatural. Each event, each "thing", is real in a physical sense or is meta-real, real in a metaphysical/cognitive sense. Nothing else, nothing more.
So, the question "what is real?" in my opinion is absolutely irrelevant, or better, is a non-sense.
Stated that everything that exists is real, we have to reformulate the Principle of Reality. The relevant question is "what is physically real, and what is cognitively real?". We have to distinguish between the physical entities, events, relation and processes and those that are not in the physical realm (commonly defined as merely imaginary, opposite to what is considered real, because "physically" real).
The discriminant stays in what we call "the Principle of Reality": everything is physically real, except the representations of Reality constructed by the cognitive systems of the cognitive agents: the living being and the automata.
The distinction between what is physically real and what is cognitivelly real is absolutely necessary, but is absolutelly wrong and dangerous to consider not real the product of the cognitive activity of the living beings (negatively named as imaginary). It is so fundamentally real, that without it the living being wouldn't be able to live, to construct the representations of physical reality, and to act on the base of that representations.
