I think I mostly laugh or sing but sometimes I've been asked a question and answer it but realize as I am answering it that I am talking about what I was doing in my dream.
hmm I have seen a sunrise and then sunset (12 hours) but don't think I stayed up to watch another sunrise. Although I think we pretty well can see a sunrise and sunset each day if we timed it right. But to stay up 24 hours to watch then continuously without sleeping? Nope.
