This happened to me and my best friend, when we were both newly installed Altar Servers. It was Christmas Eve, December 24, 2009. We were both appointed to keep the charcoals burning to be used to burn incense. The charcoal holder was located at the back of the sacristy, the place where things used in mass are kept. There were no lights there back then, so we used three candles to light ourselves. It was just past 9pm and the Christmas Eve mass still did not start so to entertain ourselves, I took my mp3 and played some music to while the time away.
We took turns in fanning the charcoals to keep them burning. When it was my friend's turn, I sat behind him and began texting. I looked over my right shoulder and saw someone who looks exactly like me. The figure was wearing the same shirt as mine, the same pants, the same shoes, with the same hairstyle. I tried to remember if there was any mirror on that area but I couldn't. So in order to confirm, I combed my hair while looking at the figure but the figure did not move. Instead it glared at me with its eyes going red.
I was a very, very skinny kid back then. When the figure glared at me, I carried my friend (who was a little bigger than me) and carried him inside the sacristy. He got surprised and asked me what was wrong. Obviously he did not see the figure so I told him as quickly as I could. We were both crying from fear. As if we needed more spooks, it suddenly rained very hard and I swear, I SWEAR we heard children's footsteps and laughter, chasing each other on the ceiling, which cannot be accessed anywhere, certainly not by small children.
Later that night, our elders found us hugging each other inside the big closet in the sacristy, eyes swollen from crying. And that, my friends, kicked us off in our adventures inside the church. We have many more experiences inside our church. Will post more soon.
