Paranoia's grasp

I went into panic, I was hyperventilating, my hands were hard to control. My fingers were trying to get something, anything, I wanted to smash a glass. Punch the wall even harder than I wanted before. I was afraid, everything was dark, the fireflies didn't help. I thought that black bars were trying to grow a cage from underneath my feet. The ground disappeared, and at the point where my despair was about to push me into mass murder. Something came out from a wall, it wasn't really a wall. It was more of a door now. But that door was not visible for me now, light was shining from within it. I couldn't understand what was the meaning of this, why would there be a door to a second room? It grew my suspicion, where is Lily?! I wanted to scream those words out loud but then I noticed that the door was opened by Lily. And she was the one that came out of the door. My heart stopped racing, I slowly calmed down and my breath stabilized.
