I'm afraid of the dark because I'm accident prone enough when the lights are on. I always forget what's on the floor. I've tripped over a vacuum cord before and almost fell down the stairs ;_; I'm always afraid I'll fall on a pointy corner and hit my eye, which I saw happen to my brother when we were kids. Blood everywhere, and the night ended in the hospital
well, if i had my usual items with me, i would have a flashlight, pencils, a snack, pop, calculator, a pocket knife, a pocketwatch, an odd hat of some sort, and a scarf and gloves, a tardis journal, and for a period of time i carried around a small hammer. using this items i could find my way out easily(or very slowly depending on if the wall was drywall or brick)
However if for somereason i lacked all of my items for an odd reason, i would probably just put my hand on the wall and walk around untill i found a door or some way out, i had to get in there somehow.
