Sure you can, its done currently for Deep Brain Stimulation. What you're proposing is "The plane of Quake isn't physical", which is nonsense.

I can make the computer imagine Quake for me, then fiddle with its plane of imagination for some sweet wallhacks.

If you create a device that can insert objects into the plane of someone’s imagination, that would be awesome :)
