the dreaming continues

we're playing on the bed this afternoon. I lie down
He lies down with me, face to face, and shuts his eyes.

Me: Are you dreaming?
Ian: Yes! I am dreaming!

we lie still for about 20 seconds, making the sleeping sound.

Ian: Mamma, get up! You are! dreaming too!
Me: Yes I am. I'm dreaming too! What are you dreaming about?
Ian: Wheels. What are you dreaming about?
Me: Fish. I always dream about fish. (True.)
Ian: NO!!!!
Me: Well, you asked. I'm just telling you. I was dreaming about fish.
Ian: NO!!!!!
Me: Occasionally I dream about babies.
Ian: NOOOOOO!!!!!! No babies! No fish! Dream about animals!
Me: I guess I could try that.
Ian: Giraffes. Giraffe animals.
Me: Okay. Let's go back to sleep. I'll try to dream about giraffes.

(30 seconds of pretend sleep.)

Ian: I was dreaming, but now I wake up. You dreaming?
Me: I was. I dreamed about giraffes.
Ian: Good.
Me: Baby giraffes.
Ian: (very satisfied) Good.
Me: What were you dreaming about?
Ian: Wheels. And fish.

(Incidentally, the internet is very obliging - I typed 'dream fish' into google, and up popped this page, which informs me that certain species of fish can be enjoyed for their halluncinogenic qualities. In the pacific, says the page, these are called Dream Fish.)
