Someone Said, "Listen to the voices within yourself"

In Hyde Park in Chicago there are street murals and art wall under the train track. The person in this video said, "It just drew him in and wouldn't let go like it was talking...so he started to listen." You can hear it too if you walk through and just...shhhh...listen...? It is said that it may not happen the first time though but don't give up, try again and you'll start to hear what these street murals are saying...Like...I've seen you somewhere before...mmmm, but where? It is eerie.
