Loosing his mind

When you walk down a straight corridor, without any changes or wind, it's like walking in a continuous calm, a strange feeling that everything was the same, any alteration in that dynamic was like a warning; that's why, further ahead in the darkness, when neither the crackling, nor the light, nor the heat of the torch could be noticed, Ikky could feel a draft from his left.

With his improved vision, he could see how the tunnel continued forward, straight as before, but his gaze went to that wall... he felt it again. In the smooth marble, the block on the right protruded just 2 millimeters. The air filtered through a thin crack.
