I read this Experiencing the Paranormalin Malaysia Airlines' blog:
Has anyone here experience paranormal in hotel? I experienced once and it's quite similar to some part of this story that I had problem with the door with my keycard. everytime I came back to the hotel room and tried to open the door, it couldn't work.. but when my friend slotted the keycard for me it worked.. that's why I was terrified...
oh I read this in Malaysia Airlines' blog when it just came out.. I think maybe it's just some illusion, just we should not think too much when we stay in the hotel, or we should request to change the room immediately if we felt something wrong with it....
