Different Kinds of Dinosaurs

I dreamed I was taking a little boy to the Geology Museum in Madison. I was excited because it was free. The kid was reluctant, so I explained to him that we'd be able to see how modern day animals are just "different kinds of dinosaurs." Right then, hundreds of giraffes appeared in front of us. I was able to tell which dinosaur they had each descended from. Some giraffes were giant, about ten times larger than they are in real life, and some were miniatures and incredibly skinny. One of the mini ones turned to green plastic. All of a sudden, I realized I'd lost the little boy, so I went searching through the geology building. I ran into professors everywhere - none of them would help me.

At first, the little boy was my brother at about 5 years old, then later turned into my friend Marc's son who is also five years old. Throughout the dream, they morphed from one to the other, and I could never tell who he really was.

Grappling Hook

Only a snippet of this dream poked thru the memory veil:

I was walking a dusty trail in The West.  Coming towards me was a wagon and a giant man walking alongside the horses.  He must have been 12 feet tall and well-muscled.  Without thinking my hand went to my gun, but he just looked down at me and smiled as he pulled back his duster to reveal the full-sized shotgun he had in his hip holster.  So I gave up on confrontation in my mind and he seemed to recognize this and dropped his coat back over his gun.  

Then, so quickly I am not able to see his movements, he whips out a grappling hook and swings it around his head a few times and launches it backwards without even looking and grapples the face off the driver.  This is not disgusting in any way as his face simply 'pops' off.  The giant laughs and I feel relieved.  Then I think "I'm not sure a grappling hook works like that,"  recognizing this as a true statement wakes me.
