I was at home after the family's new-year party, I had ceded my room to an uncle to let him stay-over at our house, so I was to sleep at my parent's studio, all this located on the second storey of a 1950's double hight ceiling concrete house, I could not fall asleep so I set up the VCR to watch "Hook" and about half an hour into the movie out of nowhere the deafening sound of a turbine on top of the house, I was startled, but foremost I was scared, truly scared. First, as I was materially shaking I ventured into the hall by opening the door and was startled by the darkness, pitch black, and the sound was louder, so I shut the door and bolted it, as the room had two doors I locked them and bolted them, then I ventured into the window that was facing the back garden, I opened it and tried to peer up into the night, but as before, everything was black, like tar, I could barely make-out the silhouettes of the trees on the back of the house, what struck me odd is the lack of down-draft that usually comes accompanied by the sound, as with any air-plane turbine, also the sound was deafening, so I closed the window, I wanted to call-out to my mother and father as well as my brother but was too scared, so as I was making-up my mind and building-up courage I sat on the sofa and before I knew I had passed-out, the next thing I remember was waking-up in the morning all startled because it all felt like a second or the blink of an eye, in the sofa and the sheets and blankets had been set-up as in a bed but too perfectly, when I clearly remember that I had them folded right besides me the moment that I sat down to ponder whether I should or I shouldn't call-out my family, I was also startled by the fact that I was lying in the sofa as on a hospital bed, face-up, arms outside sheets and blankets besides my body, wrinkle free. After I woke-up I asked my brother if he had heard anything and he told me that yes, but he was too scared to come out of his room, we have not discussed this events for years.I thought this was probably a figment of my imagination but lately, as I live in Montreal, I made a trip to Mexico on September 19th, 2011 and was singled out by TSA at the Airport for a revision, stripped-off every piece of jewellery, coins, shoes, etc. the TSA agent was scanning me with a wand when suddenly at my right foot the wand beeped and made me take my sock off, to his surprise no scar, no marks, nothing, then he proceeded with the rest of my body and precisely on the right clavicle the wand beeped again, he seemed annoyed as if he got me with a chain or something, so he kind of jerked the polo open to find nothing, because I have never had orthopaedic surgery of any kind, scar-less skin, then I could see the fear in his eyes, he just mumbled to put my socks and shoes on and to go without taking eyes off my person, with true awe and fear. I am concerned.
