There's every possibility that it is real, just as there's every possibility that things like Spiritualism and telepathy and whatnot are real. Unlikely, but still possible. Thing is, we haven't proven scientifically that these things don't exist, and we have no idea what the extent of the mind's powers, or natural laws of nature and science, are yet. There are still tons of things we don't know. So, there is every possibility in the world that all these things are real, and we just don't understand them yet. Don't dismiss something out of hand, unless you can decisively prove that it's not actually real.
