Do thoughts of accidents create those accidents?

Do you have these experiences? This afternoon I went to a mall to buy some groceries and on my return decided to walk the dog to free up the evening, when I had hoped to go dancing. Normally I wear snow pants to dog walk, but had leggings on under my jeans and that seemed warm enough. I undid a back button and slid my cell phone in, an HTC Touch I've had about a year. Doing the button up, I thought,

'What if I fall? The phone will smash.'

So I undid the button, took the phone out and slid it into a front pocket.

'That's safer.'

I can't remember if I've ever had 'a thought' travel through my mind of a potential fall before, not one where I've taken a precaution 'just in case.'

I did fall. I haven't fallen so harshly on my tail bone since my daughter was a baby, and that was skating on ice and it took a full season to heal. Eighteen years ago. Today I was playing with the dog in the snow and slid on a path that was snow-packed and icy. I lay in the snow for long minutes not sure if I had seriously hurt myself, no-one nearby. As the pain dimmed I carefully rose, on my feet, knees bent then straight, bent at the waist, then slowly lifting myself upright. Seemed okay.

Though sore. So I took Ibuprofen and stayed home and watched The Squid and the Whale, which was an emotional experience since my children also have lived/are living a bifurcated life between two households.

Back to the topic of this post. It happens. Falls in Winter. That's not the point. The point is that I moved my touch screen cell phone out of the back pocket for an event that I've never thought about before and which did happen. An accident - at the angle of the snow path to the sidewalk I'd gotten my dog way too excited and she raced towards me, careening into me and causing me to lose my balance.

Is it that we must immediately cross 'negative' thoughts with 'that won't happen' when we think them, otherwise... they happen?

My cell is safe, my tail bone perhaps a little bruised, and, yeah, lucky, but. Should I have dismissed 'the thought' of a possible fall when I had it?

Was it a premonition, or did the thought create the event?

If you've had these sorts of experiences, I'd love to hear.
