Overslept-dreaming

Among other things, last night I dreamt that I was teaching someone how to catch fireflies with a bug net, I was quite good at doing it but whomever I was teaching kept killing them. I also went eat at a restaurant in the countryside in China. I had taken the train there. The only other thing I remember is that in this dream I went to a bar with some friends, and my friend ordered a salad, for which the portions were extremely small, so he had to supplement the salad with peanuts that my friend had bought, and I also ate some peanuts. There was more, I think I also went to Hong Kong in this dream, which was rather epically long, due to the fact that I overslept by two hours. Now it is raining here and I wonder if there is a connection between rainy days and oversleeping.
