All these actually happened when I was still in Secondary school (aged 13 to 17 years) and seriously, I really have no idea was it real or was it simply my imagination. When I sleep at night, I always encountered spooky encounters, like the more "popular" 鬼压. It simply meant that there are mischievious spirits that goes around paralysing hapless humans who are alseep at night. In Western society, it's referred as 'Nightmare' and it is deifnitely not a very good experience at all. Imagine sleeping soundly at night and suddenly, lo and behold, you find yourself unable to toss and turn, and you can't even talk at all. The freaky part which I encountered was that when it happened (鬼压)， I thought I heard something laughing cynically, like as if whatever that thing was knew that I was helpless to call out for help, much less move. So, I had to endure a full agonising 15 minutes paralysed. But the next few times which I encountered it again, I was a little prepared. I sort of realised that it only happened when I sleep with my palms opened and facing the ceiling, it's almost like a "link" to my body. And if that's not enough, I got to be entertained by moving furnitures in the dead of the night. And again, it only happened when I was the only one in the house not dead asleep. Sigh... Even sleeping was getting torturous for me during my school days. Weird part was that, it started suddenly and it went away suddenly too. Like as if everything never happened at all. Freaky, right??
