During my last full year living in Taiwan (1992), I was with a friend from Liverpool named Paul, and we had just finished eating dinner in a pizza restaurant in Taipei. We were outside the restaurant on the sidewalk talking; he sitting sideways on his parked motorcycle, me standing facing him about 8 feet away or so. It was around 8:00(?) or so at night. The temp was warm-to-comfortable. Suddenly, I felt a cold energy come into me through my head, and I couldn't move or speak. I seemed to be looking at Paul through a fog, and as I looked at him, he squinted a bit as if he had trouble seeing me, then suddenly he began rubbing his upper arms with his hands. I was quietly struggling for several seconds, then the energy lifted. Paul said, "@#!*ing hell, man! Didja feel that!?"
We went our separate ways, and next morning he told me, "Something followed me home last night. I could sense it in my room 'til around 4:00 or 5:00, then it left. I only got 2 hours' sleep." Oddly enough, we never even discussed that incident again the rest of the time I was in Taiwan, nor when he and his family visited me in the States from Belgium (where he settled) about 10 years later. I have no idea what kind of entity it was, or why it targeted us on a sidewalk on a normal, well-lit street in front of businesses.
It was somewhat reminiscent (but less intense) of another incident a girlfriend and I had in Taiwan 4 years earlier, while we were staying the night at a ski resort on Mount Hehuan (Hehuanshan). I believe I've posted about it on this forum before. I also submitted it to researcher Lon Strickler at his Phantoms and Monsters site. If you google "Entity Encounter in Taiwan: phantomsandmonsters", you can still find it. That is the most detailed I've ever described it in writing, and I still left out a detail or so. He also included my account in his book, 'Unexplained Encounters'. Luckily, nothing further happened follwing the incident or after we left the next day.
I myself would never go on a ghost hunt (or to a seance, or use a Ouija board, etc.).
