Would love to capture one on a digital image or video recording device. I don't recall ever actually seeing one but I heard strange noises and felt a prescence, so I don't know if that counts as an encounter. As for believing in them, I'm only halfway there.
the right question is not if you believe in ghost and spirit, but whether it is a fact or not that there are ghost and spirit.
of course this begs the question, what is a fact and how you know etc. For example is a fact something you see or something you feel? Can things unseen be facts? Some say definitely not, but then who has seen an atom, if there is at all such a thing as an atom.
I believe only what is fact, and nothing more, nothing less. (and the fact could not care less if I don't, the fact remains a fact.)
You will not belief if you had not seen or encountered one before. My Grandma was a medium who could "see" spirit. Once there was this snake spirit that she fought with while in a trance. You will not belief but I belief seeing my Grandma "flew" with such speed. I was only about 10 years old then. My grandma was about 60+ then and imagine she need help to walk while she is not in trance. She can go into a trance by just stepping her right foot trice and chanting some charm. On the night of her wake, I saw images of Er lang shen and the monkey god accompaning my grandma in the sky. She worship the Guanyin and monkey god.
Beside that, I have not encountered any ghost or spirit yet.
It up to you to belief but everything I said here is the truth.
