That feeling when you're absolutely certain about something until someone else messes with your head... that's exactly what it is.
How is it possible that different groups of people looking through the same glass window are able to see the same thing and get the same vibe, which the fish in the aquarium are actually oblivious to? "What the hell are they talking about?" is the question in your head and you feel a bit incredulous about this new information that you have not really considered before. It's the sort of thing that would probably have never entered your mind unless it was injected into it.
And you think that these people just don't understand because they are not in the aquarium.
And they say...
I only hear what I want to.
