And my advice to you is to have nothing whatever to do with it.
W. Somerset Maugham
It took a couple of decades and a major life shift for me to acknowledge my ability to connect with ghosts. For a very long time, I just tuned them out. Now, sometimes I address them and other times I let them be. As a result, I can say haunted places and sites have a different energy about them.
That energy is a thing you can feel once you have learned to identify and fine-tune your awareness. The spaces are not all alike because, like us, each has a unique spirit essence; however, there are some similarities.
For me, the sensation when there is a ghost is pressure that feels "heavy" or "sticky". I have a sense of feeling crowded and my head feels congested. If I fail to ask permission, inadvertently intrude, stay too long or try to fight whatever impressions I get, I get a headache. It can also affect my breathing.
If I center and ground myself to allow the sensation and let it just flow through me to return to the space, I don't have the nasty after impressions. Either you feel it or you don't. Usually, after someone tells you or describes the sensation, you can place it for yourself.
For a quickie online tour of a place known to have a few ghosts, this video is the Weatherford Hotel in Flagstaff, AZ.
Ghosts are energy; and actively haunted places, for me, are work. They are not a place to have fun. The other thing to be aware of - wherever people are - there are "ghosts". They are not all the kind who haunt or run amuck in some fashion. Some appear in attempt to offer a warning or a kindness (those energies are much lighter in comparision). And some just are; we will never see them.
Whether you choose to believe is entirely up to you. One might wonder, do ghosts believe in us? And do we exist for them if they don't?
I suggest one keep an open mind and not get caught up focusing on anything that blocks your view to the wonder, joy and beauty of the present, whatever state you are in.
