Sleep talking:
I tend to sleep very lightly, my SO sleeps like the dead and has full out conversations in his sleep, he'll start talking, and I'll be able to ask him questions, etc. It's very amusing, but a little annoying to be woken up by his talking.
The two most interesting sleep conversations:
1) I walk into the bedroom, I was working shift work at the time, so my SO was fast a sleep long before I got home. As I change into PJ's he says loudly and clearly: "That's the deal!" I respond "That's the deal?" Him "Yup. That's the deal, Neil. That's the deal." Me "That's the deal." Him: "That's the deal."
I asked him the next day, and he doesn't know anyone named Neil and never has. We say, "That's the deal, Neil,” all the time as a way to end discussions.
2) We are both fast asleep, and I am awoken by my SO shouting "Wake up, we're on fire!" Needless to say I spring up in bed, ready to deal with crisis, only to find him sleeping soundly. Me: "We're on fire, eh?" Him: (muffled as he turns on his side) "Yeah."
Recently he got a mouth guard to stop his excessive tooth grinding, so now he still talks in his sleep, but it's mostly indecipherable.
