I'm afraid of the dark, especially outside, and actually OP, just looking at the picture you posted of the dark alleyway scared me a little! I hate walking around darkened houses, even my own, because I always feel like there's something creeping up behind me. During episodes of visual sensory overload, I'll sit in my bedroom with all the lights off, but I'll still keep my snake's heat lamp on so I can see my surroundings. I find dimly lit rooms cozy and inviting, but not completely dark ones.
As long as I'm with someone else, I'm fine walking around outside at night, but I hate doing it by myself; it makes me very anxious. I always have to be beside or in front of the person I'm with, because if I'm behind them, it feels like I'm straggling, and whatever is waiting behind us in the dark is going to pick me off if I don't keep up.
