A cautionary tale:
Not a natural gambler but a few years ago I was lead, via a vision into a hectic spiral over a couple of weeks which cost me about a grand. I was settling down to watch a champions league game on TV when suddenly I had a very clear 'vision' of the score, so strong was the vision that I was convinced it would be correct.
I ummed and ah'd and soon realised I had better place a bet on it, just to calm myself down. By the time I had found the number for William Hill and got my bank card ready, the game had already started! I was going to lay £50 on the score, so strong was the vision, 3-2 to the totally unfancied away team (Bayer Levekusen) at Old Trafford and United had been very hot.
This was before I had the internet and before you could bet after a game had begun. It was vey hard watching that game as one by one the goals came in and it was indeed 3-2 to Leverkusen. That £50 bet would have earned me £1,100 at 22/1. Not only did I not win it, but in 2 weeks lost almost that exact amount by convincing myself I could have another vision when I wanted, how foolish. I have only had two of these visions for sporting events and they were both correct.
