I'm going to take a wild guess that you rode over something that either penetrated your tyre and inner tube or was of sufficient roughness to create a pinch puncture.
This is nothing whatsoever to do with any conversation you've ever had or any erroneous thought you've ever had. Unless they involved you making a decision to aim at potholes, glass and thorns, when out riding.
Obviously I retract this totally if it turns out that you have spooky 'mind powers'.
