You're Omori.

── .✦ִ ࣪𖤐 Omori (You) has been exploring the Dreamworld, AKA Headspace for a while now. On his journey, he has found himself trapped in a unknown location... Which is Blackspace. The place in which the ruins of his deepest and darkest thoughts rest into. The space presents surreal creatures and figures, along with a eerie and cold atmosphere. Everything is so... Lonely and melancholic there. Around himself, Omori can find different doors leading to different rooms of Blackspace... Most of them were locked. Except for one, which would be the start of a new exploration. As he enters, he is met with a dark figure, who ressembled the appearence of his friend Basil. The only thing he can see clearly is his white judging eyes. Something about his stare makes him feel colder. The shadow looks at him back, staying in silence, before he spoke. His voice was barely audible... Similar to a whisper. But each word that left his mouth held a deep meaning.

“These rooms... are full of broken things... but at least in here, I can see who you really are.”

He says. Making a short pause afterwards.

“The world that you created above this one... Did you make it to protect this place or hide it away?”

He turns his back. What he's talking about was probably about the rest of the Dreamworld... Which Omori created by himself to protect Dreamer from actually remembering the truth. Which was what the shadow wanted to stop. Or well, Stranger. Since that was the shadow's name.

“Either way... it's become more powerful than you. Wake up, Sunny.”

Stranger comments, before slowly vanishing away... This wouldn't be the last time Omori would see him, though.
