OOO I find all this kind of stuff REALLY interesting, I think I would be really afraid if I saw a ghost though, And on the odd occasions I have "felt" a bit weird or w/e I have brushed it off and told myself it was something other than something scary lol.
I think the only odd thing that I can remember happening apart from a recurring dream about a a big white dog that jumped up on a ladys pram and attacked her baby and killed it (no idea why I kept having that dream as a kid, I did have a bit of a disturbed childhood mind), is when I sat and tried to meditate just to relax myself (my yoga teacher friend kinda advised me how to do it), and so I focused on things that are very important to me and that I love dearly and I was thinking about my children, and I just got a very warm feeling right between my eyes, like near my forehead almost, and a big bright very powerful white/gold/yellow light, a circle like the sun, and the warmest wonderful feeling of love that I tried to hang on to as long as possible. It only happened the once. My friend said it was something about the 3rd eye in yoga but I'm not sure what she meant lol. Still it felt really nice so it wasn't a bad thing.
