My girlfriend sleep talks, which is actually quite scary because sometimes you can have a full conversation with her, so it is difficult to tell when shes asleep.  However, often the conversations are really weird...
Once she woke up and asked me if I would look after her "cheese".  So I asked her what cheese, and she held out her hands.  I could see there was nothing in there, but because it was dark, I thought the cheese was very small.  Of course, there was no cheese, and I got scared by this point.  She then asked me to put the chese in the fridge, and pointed to the wardrobe.  
She doesn't remember this at all.
