Driving through daydreams

I do this a lot, mostly on the way into work. I daydream about conversations I would like to have with people where I am more confident and say exactly what I think and feel.
This morning I was daydreaming about what I might say to him and his response. But his response is not what he would actually say, it is what I want and need to hear but for this to happen it would involve a complete personality bypass, but then that is point of daydreaming, you can make the impossible happen.
I am suddenly at work, I don't recall driving. Were the traffic lights all green? What was my passenger talking about? Hope he doesn't think I am rude. It worries me that I can't remember my journey. It worries me that I have spent 20 minutes thinking of him.
