My eyes are open, but I cannot see

I am, as most know; a born again cynic. As far as I'm concerned maths, physics, chemistry etc run the universe; one is born, one lives, one becomes worm food. That is it. No afterlife, no greater purpose other than evolution, no ghosts, miracles, spirits, magic or whatnot. Nowt. It's all smoke and mirrors.
Now, that all said there is a part of me that desperately wants to be proved wrong, that in fact it isn't all cold, hard, logical reason and matter interaction; that there is something beyond what I can see - because I know many of my friends have (said they have) seen and experienced many things that I dismiss in my above statement.
So, a query to those who aren't hardened cynics like myself; out of curiosity - for those of you that believe in something, faith in the almighty, tarot, magic, spirits, ghosts... whatever - if you don't mind sharing that is - what made you realise or what did you first see or experience to show you that this world isn't just as it seems.
This is an open minded post, which I'm trying to be lately - I have no intention of treading on anyones toes regarding this, but I am curious.
