This song, as well as the atmosphere of the level in the game, reminds me of those dark foreboding doorways that I'll often stumble upon in my dreams, don't know what the fuck's in 'em but I really really want to find out. Some of the doorways are just a part of a facility and are blocked off by security, I quietly approached one once and lights above it began to rapidly flash in order to ward me away or else an alarm will go off. As I'm typing all this out, I'm beginning to feel a headache forming around my left eye, getting stronger actually. Massaging the muscles under my occipital bone seems to help.I need to know what's behind those doors.
You should keep a dream journal, make it easier to remember your dreams so you can continue where they left off.
