Dang that was the one I should have gotten.. The "shot" was the focus point of dream.
I am beginning to learn that in a dream, when something from the ordinary comes up from a dream sequence , then there is the focus point.
This professor was saying he had his truck serviced.. (oil change and such) a few months back.
I was reminding him of a lecture where at the end he cut it short so he could go have his truck serviced. It had been longer than a few months back. He then remembered as well.
Then out of the blue he started talking about being shot.
That was unusual in the conversation, so it was the focal point.
I will try to remember to remember to type what was the focal point.
