A very long dream sequence

I recently re-watched The Absent Minded Professor after many, many years. There were aspects of the movie that I missed completely when I watched it as a kid. Ned Brainard's behavior, as well as other aspects of the movie, seem to make sense only if we assume the movie is all just a dream.

1) We have a man who left his fiance standing at the alter three times. If that is typical of his behavior, how did he ever get her to agree to marry him?

2) Brainard is supposed to be a full professor, but apparently he has never published in a peer reviewed journal or anywhere else. When he invented flubber and wanted to interest the government, all he knew to do was to phone Washington.

3) Twice in the movie, head on collisions resulted in no injuries and little damage to the cars.

4) Throughout the movie, Brainard engaged in multiple unethical, illegal and dangerous acts with no repercussions. He tried to kill his rival and failed solely due to the bizarre dream physics. He cheated to help his team win at basketball, and endangered the lives of the players by treating their shoes with a dangerous substance without their knowledge.

5) All the Medfield basketball players wore the same size shoe, or Brainard was able by sight to match shoes with feet.

I could go on and on. I suspect Ned Brainard was not a college professor, with a pretty fiance, who made an important discovery, thereby becoming rich and famous. I think he was on the college's janitorial staff, but had Walter Mitty dreams.
