The pre-release clip of E Channel's 'To You, From Me' showed Sunny talking about the time she saw a ghost at Girls' Generation's dorm. 

The idol explained, "Yuri and I were first roommates in our first dorm. Yuri was on her computer while laying on the bed. Another member walked past the room and she saw me with my hair down looking at the computer monitor together (with Yuri).

But then a little later, I walked out of the bathroom after taking a shower. That member was like, 'How did you take a shower so fast? Then who was that in Yuri's room?' But Yuri told her she was alone in her room. At the time, I didn't know about that. Then one day, I woke up in the middle of the night because I was really dizzy. I was thinking, 'Why am I so dizzy?' and looked down toward the end of my bed, and saw a girl shaking my bedside to side with her hands. I wasn't sure if it was reality or a dream but I was just so scared and kept telling myself, 'No, it's not. It's okay.' I had trouble sleeping in that room after that, and I asked Yuri if she's alright and she said she was fine. So I started sleeping in the living room. Later on, my members told me about the time (they saw a ghost next to Yuri on the bed.)"

Scary!
