I heard God

[Darwinian]

I had a voice tell me I'd meet someone with glasses.

So therefore God told me I would.

The likelyhood of being told about a guy being stabbed is impossible. There was probably only one or two people in the whole of brisbane who could have met the criteria of the vision. Then there is the slight posibility that I would have a face to face meeting with them on the same day of the vision. Glasses do not compare in any way, and I bet no one spoke anything to you about glasses any way.

There are of course many explanations for this. The first is that had you not met this man then your 'vision' would have had no meaning and would have quickly been forgotten.

Secondly, you say that this valley is not the best part of town and therefore the chances of someone actively seeking someone and then discovering such a person is not as unlikely as you think.

And what about precognition? Perhaps you had a brief glimpse of the future.

Etc. Etc.
