I wasn't brought up religious, my parents I would say were atheist. I was a teenager when I lost my Dad, and didn't get to say goodbye, a week later I was dreaming my Mum was re-marrying and he appeared and gave my the biggest strongest hug, I still felt it as I woke up and I can remember it clear as day even now. That week I was back at school and kept having lots of wierd psychic moments like I could tell what people were about to say or do. It passed after a few weeks but it gave me a distraction and a belief in something else. I have had several spiritual experiences since.
I believe we are spiritual beings having a human existence. We are all made up of energy, that doesn't just snuff out when this 'vehicle' expires.
