You are dreaming right now in this moment.
You are dreaming with the brain awake.
Dreaming is the main function of the mind and you are dreaming 24 hours a day.
It dreams when the brain is awake, and it also dreams when the brain is asleep.
The difference is, that when the brain is awake there is a material frame that makes us perceive things in a linear way.
When we go to sleep we do not have the frame,
and the dream has the tendency to change constantly.
