Through interfacing with reality you are defining that reality. Rethink your senses and test your limits. Solve the five layers and discover a hidden treasure. Each layer yields its own reward, but few will make it to the end of the hunt. For each of your senses, you will need to set aside preconceptions and look to the underlying patterns within the data.
