The walking ghost in the dorm

Hi guys today I'm going to share this story of mine with you all, years ago when me and Minho we were really tired because we only slept for 2 hours a day because of the schedule, we quickly went to our dorm to wash up cause we needed to go out again,it was our old dorm so it only had one bathroom,the manager went ouy of the dorm, and I quickly went to take shower, the bathroom was infront of the hallway, after taking the shower I realized that there is no towel, so I called out at Minho "Hyung (big brother) can you bring a towel here please", there was a room in the living room on the left, I saw someone walk out from that room, so I thought maybe it's Minho, maybe he is looking for a towel for me, I waited for him but he didn't brought me a towel, so I opened the door and shouted "hyung (big brother) please bring me a towel" the kitchen was attached to the living and there was someone who walked through the kitchen to the laundry room, so I thought maybe there is no towel in the living room so he went to the laundry room to get it, and I waited for him for like 1-2 minutes but again he didn't came so I again opened the door and shouted "Hyung! (Big brother)"BUT MINHO CAME OUT FROM HIS BEDROOM!" and asked "did you called me?" I was shocked so I asked" didn't I told you to bring me a towel and you went to the laundry room to get it?" He said" No, I just heard you calling me now" it was a horrifying seriation, if Minho was in his room then who was that person? I looked at the laundry room, Minho brought the towel and I thought" there is a door at the back maybe someone came from outside" so I went to check the back door but it was locked from inside!, I still get goosebumps thinking about this, I don't know if that was my mind cause I was tired or it was something else but that person he was exactly like Minho walking through the dorm, I still remember his side posture, but now we live in a new dorm and it's much better than that one.
