Whether or not you’re comfortable with the term ‘third eye’, you do have what we might call your ‘mind’s eye’, that being, where & how you visualize things when your ‘regular’ eyes are closed.
Call it your ‘mental screen’ or your imagination, if you prefer.
The fact is that you can see things in more than one way.
In fact, we might even suggest that while seeing the world through the ‘regular’ method of light input into the eye sockets is both important and fascinating, seeing the world with your eyes closed offer a clearer picture.
