The boy with the glasses is trying to get some sleep. This boy is experiencing some difficulties achieving his goal: to sleep well. He takes off the glasses and start wondering a parallel universe, a parallel reality, future, etc.. Then he is flying through those thoughts and imaginations, seeing what could have been, how could he be in another life, in a different future. He wakes up. Again. Frustrating, just fell asleep and now he is awake again. Time to put bak the glasses. The day after has come. Now it's time to try to live it better than the one before.
