A doppelganger is a ghostly double of a living person that haunts its living counterpart as we all know and I have never imagine that I would be meeting such as this one.
This happened about a couple of years ago. One night after I got home from work, I went straight upstairs, which my sister and I share.
We have a bunk bed adjacent to the door, and when I entered, I found my sister on the upper bunk, facing the wall.
I thought she was already asleep, so I never bothered turning the overhead light on, instead, I used the small lamp on our side table parallel to the bunk bed.
After a minute, as I prepared to take a night bath, I heard her giggle, I looked at her wondering if she was laughing in her sleep, or if she was still awake just reading something in her cellphone.
“So you're still awake?” I said to her, but she didn't reply.
I grabbed my towel and went downstairs to the bathroom. When I got there I found the door locked. I knocked and asked who was in there, and to my surprise, I heard my sister answer from inside.
At first I couldn't believe what was happening. I just stood there in front of the bathroom door, and shifted my eyes to look the stairs. Something was telling me I have to go back and see again if there really was someone on my sister’s bed, but after I returned in our room, the person I saw there before was already gone.
I told my sister that night what just happened but she didn't believe me. Next morning I told our mom while we were having lunch. She just told me that it was just my imagination and since im tired from work, probably im just stressed out, which I doubt about it.
