Well, i cant say i have seen a ghost myself but my mum has and my brother in law has.
mums story -
My Nanna past away in 1997 and the night after the funeral my mother swears that when she was lieing in bed that she saw her mum (my nanna) walk past her bedroom and walked into my bedroom and watched me as i sleeped. (my bedroom is opposite my mothers). I like to think that my Nanna is my guardian angel.
Brother in law story -
Ohk, i hope i get this correct. My brother in law works at a raaf base, and he use to work with the dogs ( you know the ones that attack the bad guys
) well he was working late one night and took one of the most nastiest dogs outside to patrol the perimetre of the base. There was fog, and it was cold - you know the perfect setting for something scary to happen. Anyways, at one particular part of the base, theres this old shed where a longgg time ago someone hanged themself. As they walked past the shed, my brother in law (BIL - shortened) felt this odd presence behind him - not knowing who or what it was. As he was a bit freaked out, he yelled out that he was going to release this dog of the chain, as the dog was all fired up and wanted to attack this thing that was around them. Nothing happened, so my BIL yelled out again and tried to contact anyone on the walkie talkie but there was only static. So at this point in time, its night, alot of fog, there was something creepy around, the dogg was barking its head off trying to go after this thing and there was no one to contact as the walkie talkie was producing static. So BIL let the dog of the chain in which it ran as fast as it could and out of sight. once he found the dog he noticed that the dog was quiet and shaking - rather odd considering it was the most nastiest and frightening dogs on the base.
I havent heard that story in awhile but im pretty sure i got the majority of the details he told me. Freaked me out when i heard it
