Apparently, there was an international sporting event where people would try to rattle phones. There were four top rattlers being announced while I grabbed the phone in real life and hid it under the covers. When Leo started playing with the phone charger, the dream modified to fit that too.
I'm willing to send Leo off to represent the US in phone rattling if it'll get him out of my bedroom in the wee hours of the morning. ;-)
Definitely OD'ing on the Olympics when my cat rattling the phone becomes an international sporting event.
