Footsteps require a physical body. It needs weight and movement to create footsteps. So a 'ghost' couldn't do that as they don't have a physical body so there has to be another explanation.
I agree with PP that challenging belief in ghosts is part of a much bigger picture of beliefs worldwide that is important.
I would never be rude and I have the utmost respect in other people's beliefs but where they are wrong it should be challenged and 'agreeing to disagree' is fine if it was just one person who has seen a 'ghost' and leaving them to that belief isn't harmful.
But the bigger picture is seen in my years working in MH with other communities. Muslim individuals for instance who think they have a 'jinn' attached to them or Jamaican migrants who believe in 'duppys'.
I can say I respect your beliefs but actually, you hearing voices or feeling that this spirit is moving things around in your house or touching you at night is a symptom of mental ill health. Because if I didn't say that, I couldn't help you get the treatment you need that can make all this go away.
And in no way am I saying that people on this thread have been mentally ill when they've seen or heard ghosts but challenging these beliefs is extremely important when the bigger picture is having a 15 year old psychotic boy be 'exorcised' including sleep deprivation, violence and terrifying shouting and wailing all around them. I have dealt with the aftermath of this and it was horrific.
And as I've said before on this thread, if someone posted a thread saying 'help me, my son is possessed' every response would say no, he isn't. There is a rational explanation, you and your family need help and support. Because we don't believe in demonic possession in the UK anymore.
But with 'ghosts', with our hundreds of years of ghost stories and ghost - hunting tv programmes we say 'well, you never know. ..'
