Waking Dreams--Lagniappes of the Spirit World

By "waking dreams" I mean dreams that I have just before I wake up, and just as I'm waking, so that I remember them, in all their curious detail, for the rest of the day--and sometimes longer. This morning's wake-up dream: I was in Brazil--Southern Brazil, judging by the delicious temperate climate--living with a large upper middle-class family, learning Brazilian Portuguese by total immersion; joining the family on delightful excursions, wonderful neighbourhood parties...Effortlessly, I was learning to dance the Samba, and joining in the singing....But I kept missing things people were saying; such that I hurried first thing to my computer as soon as my eyes were open, to find the Brazilian Portuguese language tutorials, dictionaries, and grammars--to see if I really had been conjugating irregular Portuguese verbs in my sleep.
