Hahaha, you should definitely plan a trip to Bhangarh Fort. It is the one of the most creepiest place. Before you reach there you hear all sort of stories, and by the time the sun sets (although the gate closes there by 5 PM), you will be anyway scared on all the little things you find in those small dark cornered places around the fort.
No, as such i didn't see a ghost. But when i was returning i felt a negative energy. When i was going inside the fort everything was normal but during returning i felt like someone is following me so my heart rate and speed both were increasing automatically. I was only thinking to come out of the fort asap. I went to fort at such a timing that when i reached the main fort sunset had occurred and there was no other person there.
