On paranormal experiences, I experienced it twice. The first time was when i was on the 4th floor in my primary school out of a sudden, the head of a girl popped out in front of the window that was facing the highway. It was as if the girl jumped up and her head was just above the window and she let out a little squeal before she came down again. Me and another friend who saw it rushed to the window, looked left, right and down but saw no one. Nobody would be able to run that far and there is no way anyone could climb up there and jump as it was very dangerous and there were walls and barricades everywhere. It was freaky as nobody could explain what or who she was and how did she get up there and how did she manage to disappear so fast till this day, it remains a mystery to me.
The second time was when i was doing exams during my middle school. The classroom was at the ground floor and it was facing a field. On the far corner of the field were some bushes, and at the bushes was a very clear and distinct shape of a man, walking, but his body was transparent, the way one would see a glass of water. Although transparent, the image within his shape appears distorted like methane. he was walking into the bushes nearby and disappeared. The first time i saw him, i thought that my eyes were playing tricks on me and I rubbed them a little. The figure was still around. Not too long after, the dog that was sleeping in the middle of the field howled and he went to the side of the classroom to sleep.
I have not have any more encounters since, and for now, I do not wish to as I am not well equipped enough to deal with them.
