Have a second to think about this:
When we dream what do you think happens? Well, we simply escape from our mundane reality via our bodies and journey to another world not measured by space or time. That is, the Dream World.
Now, i think we can both agree that when we Dream travel to another world and explore the many different aspects of our dreams, we tend to feel certain emotions(some of course, a lot stronger and more realistic than others) that come with the dream experience correct?
Well then, this portrait which you see now, casually represents all the emotions that i once felt from a very long dream i had 2 years ago - from the very moment i fell into that REM state, to the moment i woke up screaming in fear.
