Mythical Creatures

What if the world was full of magical and mythical creatures whom all have certain roles in this world? Maybe they are hiding in the small cracks between one universe and the other, maybe they are too tiny to see in human eyes, maybe they are in disguises. 

These are some mythical creatures that I believe I caught a glimpse of in the corner of my eyes, right before falling asleep or merely staring far into the void.
