So you agree that we can, at least in theory (and probably soon, in practice), read thoughts?
Oh, and our brain is much more than a passive receiver.
For instance, there are just as many, if not more, neurotransmitters going to our ears and eyes as there are signals coming from them, which means that our brain is essentially telling our senses what to see and hear.
The 'colours' that we see are not, in a certain sense, real, nor are the sounds we hear.
Just like sounds are frequencies and intervals of vibrating air (or a similar medium), the various wavelengths of light are represented as colour.
Which makes the age-old philosophical question of whether you see the 'same' colour red as I do obsolete since it really doesn't matter.
