@OP You have not defined the parameters constituting what IS real. Think about this; is your keyboard really black? No, it's every color EXCEPT for black because every color of the visible light spectrum is absorbed by your keyboard except for black which bounces off and into your retinas. Furthermore, this one should blow your mind: A group of scientists, mathematicians, and computer scientists came together recently and created the equations and lines of code proving a theory that our known universe CAN be just a computer simulation. They even created a single, extremely tiny and efficient computer code method that simulates the actions we perceive as randomness. The only thing we are missing right now in order to prove this theory is the power source required to supplement the required processing capabilities. Think about the game "The Sims", we could just be a game like that for some geeky 9 year old out there and not even realize it.
One more note....Your question would mean that any individual with a handicap limiting one or more of their sense (sight, sound, touch, taste, smell) is not real; they don't actually exist. So that would then mean that we are seeing "someone" that DOESN'T exist and in turn means we ourselves do not exist...Unless you never met a person with a handicap of this sort, then you MAY exist. However, the fact that you are reading this would mean you DON'T exist since I have met MANY blind and def individuals in my life.
Something can be real to a person but does not involve the senses: this is the experiential approach. For instance, I can compose a piece of music in my head sitting motionless, alone in a chair in silence. While it is only in my head, I can go write those notes down on a page at a later time, thus bringing it into the realm of the standard senses. The piece in my head thus most certainly exists and can be fully realized in the real world if desired. The problem with arguing that creationism is real (because it clearly can exist as a concept in someone's head and be written down), is that it is not an aesthetic object, nor could it ever be. The question as to whether an aesthetic object is true or false is irrelevant and meaningless, but it is however, of critical importance to any concept, belief, theory or notion. Thus, creationism may be real as a concept/belief, but that does not make it true or reality in any way shape or form.
It can still exist because of second hand detection methods. Really all of the senses are some iterations of a chain interactions. You dont necessarily need one of your 5 senses to fire to be able to detect something exists. There are much more exact ways to mock that same type of detection using elements and machines that are more in tune to a particular type of energy.
