shimla has a lot of ghost stories associated with it. There's one about tunnel number 103 on the Shimla-Kalka railway line that has the ghost of a British sahib.
The ghost in tunnel 103 is said to be one that talks back in full context with the humans he comes in contact with.
The tunnel itself is wet, damp, dingy and about 140 yards long and is quite a scary place.
It is also unique in that the spirit of the Englishman responds to humans.
There are different kinds of spirits. Most of them don't acknowledge your presence. They just appear on a particular day at a particular time and play out their part as if on a video tape -- for instance if a woman who walks in from one direction and ends up jumping in the well will do so even if you try to stop it.
If you come in her way, she will walk right through you. If there is a house built in her path, she will pass through the walls. There is nothing you can do to stop her or even if you try to talk to her, she won't respond.
But besides the tunnel itself Shimla has a lot of villages around it and the only way is to get there is by walking. There are a lot of stories about witches in the area and walking down those was quite terrifying. These trails are very, very scary. As you walk, things move around you and you can hear them. It can be frightening to walk down these trails in the nights.
