As such, I just keep my experiences to myself. At best, it attracts the wrong sort of crowd. At worst, people think I'm insane. Thankfully, a handful of people were with me during some of these experiences and they know I'm not making things up, so I don't have to live completely alone with them. It does get isolating sometimes, though.
Good friends are the most valuable resource, IMO. Those who don't need to bolster themselves by offering unsolicited advice or pushing their understanding on others. Those who can listen and contain what they hear.
I count myself lucky to have some good friends who are into exploring and discussing things like ghosts without requiring me to buy into their narratives or wanting to adopt mine. This forum is one such place, at this time.
In this spirit, here are my ramblings:
I've never had an experience of a ghost, but I have found a few places which evoke a strong impression of being haunted, for lack of a better, more specific term. One such place is a small strip of woodland sloping down to the river in an otherwise unremarkable part of the upper Rhine valley, between Basel and lake Constance. A few hundred meters across, less than a kilometer down the valley side, crossing a road. No buildings or ruins or springs or rock formations, just a wooded area with a hostile atmosphere. Many people noticed this, even those who just drove along the road.
How to explain this? Which frame of reference to choose? Why even explain it?
For me it is sufficient to acknowledge the sense of being unwanted there, and to walk further along the forest path and out if the area. Others feel more comfortable giving a name to their experience: A forest inhabited by a fierce spirit, or echoes of a great tragedy in the past (unrecorded in any local chronicle I checked), or the slant of the light into the valley, or picking up on the uncomfortable feelings of those "in the know".
I think these attempts at explaining the experience are intetesting but don't address the immediacy of the "something wrong" impression. To make a feeble analogy, it's like the difference between appetite, which can be triggered by external factors like pictures of tasty food, and hunger, which is caused by internal factors like depleted nutrient depots. The feelings evoked by the haunted forest arise from the inside, like hunger, not from external factors such as apparitions or spooky lighting.
