Well I stumbled upon this website through the power of Google and Wikipedia. It seems I suffer from excessive daydreaming, although there was never a term for it to me before I've always know my triggers: music, reading, TV or anytime I'm alone. I guess you can say it can pop up and me not realize it's happening, I could be in the middle of a conversation with someone and just switch into DD mode, sometimes it's a gift and other times it's hazardous(especially when I'm driving and happen to have the radio on). I can't say I'm not happy I have an active daydreaming mind, but I wish I knew how to control it better.
