Allergy meds are messing with my dreams

My allergies have been quite bad the past couple days.  I've upped my dosages of allergy medications.  

Which seems to have turned my dreams into a surrealistic movie.

World War II, but with modern technology.  Military captain rescues Shirley Temple, blond curls, perky smile, and all.  Takes her on a jet that is flying a mission over the US.  The jet gets shot down. 

We cut to a scene in a control center where there is a infrared-like display. It shows pieces of the jet falling towards buildings in a big city. It also shows Shirley and someone else falling from the plane.  Shirley is holding a saxophone.  (?!)  

Shirley lands face down in the grassy front yard of a home.  (No saxophone.) Mother and grandmother are watching 4 kids, with 1940s clothes and haircuts, play in the front yard.  (Wasn’t there just an aerial dogfight overhead?) 

The mother goes inside to call authorities.  Grandmother says “Don’t touch it!”.  Kids sidle past to get on porch with Grandmother. 

Shirley comes to, completely unharmed.  Gets up, sits on the porch steps and talks about “Have you been to the zoo?  I’ve been to the zoo.  We should go to the zoo.” 

Meanwhile, the kids are edging away from her trying to get to the door to the house. Grandmother keeps saying “Don’t touch it!”. 

I've read that dreams are the brains attempt to process new information.  I have no idea where any of this came from.
