Darkness in the light

"H-How did you know?" John asked 

"So it's true... And are you really asking me that right now? Especially when you enthusiastically shouted out in the middle of the city 'THIS IS ANOTHER WORLD!'" She said 

John was speechless, not because she found out, but because of the way she found out. 

"W-Well, It's part of life." Said John 

"There are many questions, I'd like to ask, but I'm afraid, we don't have much time..." 

After she said that, John looked towards the other side of the room, quarter of it, was clouded in darkness, he had no intention to approach it. 

[Since this is inside of my mind, that must mean that there's darkness in me... Not that I mind, if it makes me stronger.] 

The lady then looked at the light ceiling, confused, John looked as well, but it was just a regular ceiling. 

"Wasn't there something you were going to tell me?" John asked 

"Hmm... It's still too soon"
