Guarding the Office at Night

This is a translation of an anonymous creepypasta posted on one of Russian imageboards long time ago.
I’ve never told anyone this story, and I don't think I ever will (unless, of course, I get found out). I used to work as a night watchman in an office building in Russia. I didn’t have much to do, just to stop anyone from breaking in (I am skinny as fuck, but if someone could break through that tough iron door, even a SWAT team wouldn’t stop them, so I was there just as a formality), to let my bosses in and to check if the ceiling was leaking – sometimes a pipe on the second story would burst. Also, I had to clean the windows once a week. Basically, my work was pretty skate. There were also computers with games like Heroes of Might and Magic III – and I didn’t need anything more. I spent every Saturday night in that office. Things were quiet, as only three people had keys – me, a director and some manager. One Saturday night I was playing on the computer when something rustled behind the door. Just once.
I got up and looked through the peephole, but nobody was there. I thought it was someone just passing by and got back to the game, but then something scratched at the door, and I heard an indistinct male voice. I thought it was the director, so I put the key in, turned it once and then looked through the peephole again. I said, “Is that you?”, but nobody answered. I turned back the key, and immediately I heard a voice from beyond the door. This time it sounded like a woman, but I still couldn’t understand a thing. It seemed like it was saying something, but not a single syllable made any sense. I swore at them and threatened to call the police (I was bluffing – we had no phones in the office, and the whole thing happened before the age of cell phones). A moment later, the female voice shut up, and I heard a quiet knock in the window. I opened the blinds, and I was stunned. No, I was paralyzed with fear.
My legs buckled, and I sat on the floor. A man (I want to believe it was a man) was hanging on the bars. Everything about him was completely unnatural. It looked like something that had only seen humans in the movies before had made a human suit and put it on. I couldn’t even approximately guess at that thing’s gender. Once it saw me, it started to speak – first, with the same female voice, then it started to alternate with the male one and then it seemed like the sound was coming from different sources, interrupted by some scraping and rustling. Fuck, even its facial expression was absolutely inhuman – it was moving its facial muscles in all possible directions. The creature was pressing its hands and legs at the glass while somehow climbing up at the same time. Maybe it was squeezing the rods with its knees and pushing itself up, I don’t know. Back then, I thought it was flying. I could see the thing very well, and it hung for a pretty long time, perhaps for a minute. All that time I couldn’t do anything – I just sat on my ass and stared at the creature.
About a minute later it finally ended – the whole cacophony died down, the thing turned back abruptly (I swear its head turned all the way around) and froze for a few seconds, staring at something. Then it suddenly jumped down and ran off while screaming something in a new, high-pitched voice. Since I was sitting on the floor, I couldn’t see where it went. All I could do was close the blinds and crawl into the office where I couldn’t see the door or the windows. I sat there and cried like a baby – it had been eight years since the last time I’d cried. Then I stopped and started to shudder all over. I sat on the floor till six in the morning, when my coworker, Artyom, came to replace me. I looked at him through the peephole for about two minutes asking him either to step back or to say something before I opened the door. 
Finally, I let him in, and although he slapped me on the back of my head, I just laughed hysterically (until I started to cry again). Anyway, when I came home, my parents had no idea what had happened to me – I was pale, I had circles under my eyes, and when I weighed myself, I found out that I had lost fifteen pounds that night. Since then I often have trouble falling asleep at night, and I get nightmares. I never told my friends about it, since they would only laugh at me. I decided to post this here, because even though you won’t believe me anyway – at least, I wouldn’t believe it myself - I really wanted to share my story. Well, that’s all for now, I’m going to try to go to sleep.
Why didn’t I go insane after that night? Thinking logically, I can say that if that thing had wanted to get me, I wouldn’t have been posting in this thread. It seems like that thing saw me only by chance, but then it got distracted by something else and forgot about me. At least, I want to think so.
