I'm a pagan, so this is from a pagan perspective.
I too believe in ghosts, I have even had several encounters with such entities, as have most in my family for generations. there is a psychic line on my fathers side of the family you see. Note mind reading or anything, just a high sensitivity to spirits, the males seem only to be able to sense and feel their presence ( see on rare occassions). The females are a lot more sensitive.
there is nothing wrong with wanting to see a spirit. Curiosity is a natural, and very human thing. Just know that it is not the most fun experience, depending on the spirit you see as well. It has always been a quite 'weird' for me. Even though I've only dealt with benevolent spirits,I still get the shivers and feel a little scared. I can't imagine how it would be if I had seen a malignant spirit, or a poltergeist.
Spirits can be dangerous. They can also be very friendly, even helpful. just be careful if you intend to seek out ghosts. You never know if they are bad or good. They can lie like humans, and you generally get back what you put out with spirits (from personal experience). Just make sure you want to see one for the right reasons, and if you do, use some protection. salt is good, if you don't mind using white magick, visit my site:
P.S. If you plan on holding a seance or summoning a spirit, please cleanse the area and any tools you used afterwards, you don't want malignant spirits hanging around (that is if they came through the doorway you opened).
