Where am I at?

I'm in between two walls, two extended corridors long. My head is feeling high on alert inside of this darkened hall! I feel like if I continue walking there's a spot where I might fall. There's no clear view of the floor at all, and I'm afraid to go further with the thought that I might fall! Now my thoughts are rolling on a ball, the path ahead is spinning and there's a quick acceptance that I'm lost falling over me now. It's more than ever now that I wish I had someone to call! Where am I at?
