Grasscarp, please don’t let criticism upset you. I’ve had some very heated discussions with the people I respect most on here about ‘ghosts’ – but we haven’t fallen out over it. :o)
When people who have no experience state categorically ‘there are no such thing as ghosts’, they probably don’t realise it but they are actually accusing the witness either of suffering delusions - or lying – and often they are neither. Of course many people do imagine it – easily done in a dark room at night - but certainly not all. I saw a ghost on a Saturday afternoon in broad daylight. She wasn’t diaphanous – she was solid – she wore fashionable clothing and her hair-style was up to date. Initially, I saw her reflected in a mirror, but she was still there when I turned to face her full on in order to look at her properly – and she was still there as I walked across the room to the door and left. She shouldn’t have been there, but she was.
Of course the real problems arise when things go bump in the night – and in the day – for no apparent reason, but which actually, physically, disrupt lives. I lived in a ‘haunted’ house – and it wasn’t pleasant. I have no doubt whatsoever that things happen in this world for which we have no explanation.
