Ghosts do exist and science has proved it. absorbing materials such as stone and water absorb energy and every now and again it gets thrown back out. so if you have been sat in 14th century waiting for a loved one to return every day by the same window for years, that image every now and again gets thrown back out again. its not paranormal at all. you cant speak to it, it wont reply to you if you ask it for a cup of tea.
Spirits are the ones that you can have a conversation with, with tapping noises, speaking via white noise, touching or throwing on command etc.
spirits are the ones that scientists are trying to prove/disprove. It will always be a debatable subject, heaven and hell, spiritworld / just die and thats it. No-one will really ever find out the truth until it happens. theres always a photoshop for pictures so even the genuine ones now will get the flack. I always say the only way you beleive or not beleive is to experience it for yourself, go to a haunted location on a ghost hunt with all the techy equipment. we do them every weekend and more and more swaying to beleivers now - weve seen too much lol
