sweet dreams

I had one of those lovely nights last night - which occur only two or three times a year, I find - where I had a number of (I should specify for clarity: non-erotic) dreams that I found so enjoyably funny that I actually woke up a few times laughing. I cannot remember much about them now, but it has left me wandering round this morning as if surrounded by a velvety cloud of good cheer, and smiling has been my default expression.

Anyone else ever get this?
