What do Toddler's dream of?

[liralen]

The other night, when Jet came, crying, into the bedroom, and I picked him up and carried him back to his futon, he muttered, "Flying. Flying plate crash fast." And he burrowed into me when I laid him down, smiled and went back to sleep only to mutter, "Dough train yellow."

Makes my brain hurt wondering what those words were actually describing.
