I am not quite sure why people want to be ghost hunters. If you have a need to communicate with the other side - just ask. It makes me and many of the spirits I communicate with laugh when people use all kinds of contraptions to communicate. From what I have learned all you need is an open mind and an open heart. Be sure to ask your own spirit guides or guardian angels to protect you. This keeps out any unwanted guests. I am a Reiki Master and Teacher but I find that the healing provided is usually way beyond Reiki. I don't ask, I just offer healing to those in need. Just like UPS - deliver the healing energy to those in need.
I live in an old farm house and I have many guests. These guests were former residents of the house and I thank them for sharing their home with me. I find that spirits usually hang out in a place that makes them happy (you would be surprised at how many spirits hang around a family reunion or event)or sometimes one that brought them pain or sadness. Most are not "stuck" Some are still trying to heal and have difficulty letting go.
I have a picture of a street in Old Orchard and in the picture you can see a figure in the picture leaning against a wall. He is not stuck - he just likes Old Orchard Beach and people watching.
I and many people like me go about our daily lives and communicate with the "other side" on a daily basis. It is really not such a big deal. It is very much like communicating with a friend or mentor. We use no props, candles, crystals and such - we just talk and listen.
You would be amazed at how many people communicate with spirits but are afraid to admit because they are afraid of being ridiculed.
Is there life after death? Definitely! I experienced a "near death experience " a couple of years ago and it is definitely quite the experience.I have communicated with many of my deceased friends and relatives. A couple of them were a surprise - never knew they passed.
People talk about orbs in pictures and I have many pictures taken at my house and the pictures are full of orbs. Sometimes I can look in the distance and I see thousands of orbs. So, I believe that what many call heaven or the afterlife is all around us.
People hunt for ghosts or spirits and in reality they are all around us.
My belief is that we formulate a life plan before we are born in which we agree to follow a predefined path. It is a path of learning and one we repeat many times.
Oh, if this is the group that made the "buck an ear" joke for the pirate - he was very amused. I also hear that spirits are sometimes confused and sometimes rather amused when people call on them and then run when they speak.
Just a few observations - I respect people and whatever they believe. My comments are merely my opinion based on my experiences and communications.
One thing my spirit guides have taught me is that if you make a promise to never hurt another human being - it pretty much covers it all.
