Um, I really doubt it.
At least I was already awake, if only barely, and even out of bed, when the phone rang.
I shouldn't still feel tired, considering I got offline around 10 and went upstairs not long after. Finished reading the interview with the Google guys and a scary article about electronic voting machines in this month's Playboy, then turned out the light. The Mountain Dew with dinner certainly didn't affect my ability to fall asleep!
Fairly vivid dream in between hitting the snooze button on the clock-radio and actually getting up, featuring a particular person who hasn't played a role in my dreams in a while. Weird.
