Ok then. But not bushcraft related.
I've "seen" ufo's on 4 separate occasions in my life. 3 times on my own and once with a friend. I wont bore you with the details but each time was completely different with different types and numbers of craft involved. Im more than happy to put these down to some sort of illusion/hallucination/whatever and would not put them down to little green men as many would. The mind/consciousness is a fascinating subject that science is only just starting to scratch the surface of.
The one thing that has happened to me that I cannot for the life of me explain was as follows: I phoned up my friend to arrange to go out for a drink and his father answered the phone and explained he was already out and which pub he was at. I thanked him and went out. On getting to the pub I found the atmosphere with my group of friends was somewhat subdued. I was quckly informed that the friend whom I'd phoned Dad had died the previous day. I thought it was a wind up but thankfully I never mentioned the phone call because it was true. He lived alone with his Dad and there was no uncle or anyone else it could have been. I'd known his dad for many years and knew for a fact that that's who I'd spoken to on the phone. It kind of rocked me because Im an athiest at heart and just don't have an explanation for it.
On the subject of ghosts and the like. Well apparently they can create them in the laboratory now. Not sure how, haven't done a search or have any links but it's something to do with sonic frequencies or something like that and reverb in cerain spatial conditions. It can make people feel cold and hairs stand on end or "see" things that aren't there or "feel" a presence and uneasyness, that type of thing.
As far as people being absolutely sure they have witnessed something (including my own example above) think of this. We've probably all been in the situation where we've been speaking with a couple of people and someone points out we said a word or name or something wrong. We argue that we didn't, we are absolutely convinced we didn't say what they said. We are as sure as anything and would bet our life on it, after all "we" said it, so we should know. Only, the other person present confirms that we did indeed say something different. Suppose this only goes to show how easy it is to fool ourselves sometime.
Hope that made some sort of sense
One other thing. I used to be terrified some evenings when i was awake in bed and felt a presence in the room and be paralysed with fear. I was convinced there was some sort of malevolent source to this until I found out about sleep paralysis. Thank goodness for science
There are a lot of anomalies in this wierd and wonderfull world of ours. The human mind is cabable of creating it's own universe within itself. I don't believe in the supernatural, it's just unexplained normality.
Makes a great story though
