I had similar experience but different hotel (chateuu rawang) . It was at balcony area where the environment had the spooky look.Imagine cracked wall with spiderwebs and aging wall paint.The time was 12.30am ,I was sitting on the sofa and suddenly out of nowhere came a grim sound of something heavy being dragged accross. It was so great that i had to shut my ears. 1 minute later i entered the VVIP room situated next to the balcony to find out anyone of my family had heard the noise but to my suprise no one. After reading the experience above i’m somewhat relief that it was not imagination and someone else had similar experience before.
