We used the roof as a place to go an smoke cigarettes. You had to get through the attic to get there though. There were no lights so the only lights we had we from our shitty flip/brick phones.
One day, my friend Manny and I were going up to smoke. I told Manny I had to piss, so I did in the apartment.
I went up and felt like there was someone there. It was pretty common for us to mess with each other, so I said, "Manny, I know it's you. Quit fucking around. I followed this shadow figure, thinking it was him.
I yelled, "Stop playing, I know it's you" as I followed this figure. Then I heard, from downstairs, Manny, say, "What?"
I was terrified. I had just followed "him" to a corner. I ran back downstairs and asked if he was there. He was, talking to his gf at the time and I told him I didn't want to go upstairs.
I know what I saw. People always try to say "maybe the shadow was your own" That's not possible because I had a Motorola flip phone at the time and I was only holding that in front of me.
I saw a shadow person, and I know others have too.
