Do you believe in signs?

Earlier today I sat down to create a spreadsheet of the publishers I plan to query.  As I was creating the spreadsheet, my computer went black.  My first thought:  "Is this a sign that I am not ready to submit this story?  Should I wait?"

I shouldn't jump to conclusions, though, because my computer does this from time to time.  Plus, today when I tried to do a Java update, some weird thing was installed on my computer, which I believe is causing the problem.

ANYWAY... is this silly for me to believe in signs?  Do you have thoughts like that too when important work is interrupted?
