Dream Dimension: My Reality Reversal is too OP!!

At the age of sixteen, every human awakens a Dream Mark, granting them access to the Dream Dimension—a boundless world they can enter whenever they sleep or meditate. Within the Dream Dimension, everyone awakens as a random Dream Race. Dragons, Angels, Vampires, Slimes... or countless other races. This Dream Race becomes their true form in the Dream Dimension, and every bit of strength they gain is reflected in their real body. Death, however, comes at a terrible price. Each time someone dies in the Dream Dimension, their soul weakens. When it can no longer endure, they die in both worlds. Liam Heart enters the prestigious Twilight Dream Academy, where students awaken their Dream Races and learn to survive the endless Dream Realms. But while others rejoice over powerful races, Liam awakens as a Cursed Eye—a tiny one-eyed monster whose only ability is to inflict a weak curse through eye contact, an attack so easy to avoid that it is considered weaker than a slime. Everyone believes Liam is destined to die within months. Three months later, when the entrance examination for the Higher Dream Academy begins... Liam stands at the very top. — Description from novelcodex.org
