Have you ever waken up from a dream thinking that you are back to the real world, then later woke up again and realized that you were still in another dream in reality?
That was what happened to me last night.
Now the question is ... Am I still in a dream and can wake up any moment to another “real” world? :-)
I have been reading history books and watching TV documentaries of historical events. Such activities are more or less like time traveling for my mind when I am awake.
At night, my brain was probably trying to process all the information gathered in my mind from the day, and created a hierarchy of dreams.
Just a thought ...
