I was getting hell bored yesterday night so I started watching some MVs of Super Junior. After a while, I saw EXO Growl MV beside. I had heard that it was good so decided to watch it for the first time ever. I saw it and trust me, I was actually enjoying it but... what I saw later scared me. I'm a pretty good observant and tend to observe things that I should and many times... that I shouldn't.

At 1:10 in the video, I thought I saw boy at the window behind the dancing members. I thought that it might be a worker or something but then, when the lights were going off in the background... the boy disappeared and then appeared again when the lights were on. I was like 'what the hell just happened?' I thought it was just me imagining stuff since I had watched Conjuring just an hour ago. I continued watching the video and I think at 2:57 or something, I saw a shadow walking into the wall... how is that possible? I replayed that part again and got terrified. I thought I might be hallucinating so I saw another SJ video but didn't see anything. Then, I watched Growl again and I saw those things again. As the 1:10 part came, I heard a knock at my door. I got so scared that I just threw my tab aside and hid under my blanket (It was 3:30 in the night!). Today, I asked my parents if they had knocked the door, they said that they didn't.... I don't know how to interpret this! I don't think I'll ever be able to watch Growl again.

Can any of the EXO fans tell me what exactly was that? Is it just me who was seeing things...?
