LMR's Mental Adventures

So let's begin this:

Well last night in my dream it began with me coming out of portal and seeing a kid and his family in a spaceship car. I walked up to the kid and say "you're my grandson and also you're the last "who" (like an entire different race, Dr.Seuss created) their is". That's all I remember of the beginning, but I do have some more fragments.

I think I was running out of the drivers ed class because I was running out of time to save my grandson (who was considerably more attractive than me, and many people told him that throughout the dream). My other grandson, his little brother, ran into the class and told me "we have to do this, NOW!". So that's why I was running out of the class. We ended up at a balcony and just as we were going to use the time machine (the really spaceship car thing) broke. The other grandson pulled out a handheld time machine and said "just for backup" we jumped over the ledge and just as we were going to hit the ground he clicked the button and we were on top of a falling rock, the rock hit the ground and softened the blow. The view switched and I saw what happened when the rock hit the ground, well when the rock hit the ground it hit in a way that the cracks created a date or an address I think it was something like 7/12/1... or an address. After that I remember thinking "I am a genius" and after that it gets blurry.
