What purpose does dreaming serve other besides to solve problems and to keep our minds working even in sleep?
Coping with stress,
re-evaluating the data you absorbed during the day,
fantasising, hypothesising, ...
Seems enough purpose to me already,
but there is probably more ;)
it is just your subconscious on autopilot...if you have the awareness you can take control at any time.
Ever since I have been having intentional OBE's while awake, I have been in contact with my spiritual guide. He has told me that dreams also serve the purpose of informing us of our fears, worries, and weaknesses that we must work on in life. We are supposed to overcome our fears and worries and improve on our weaknesses. I have noticed that most of my dreams lately have been dealing with fears that I have. So, I have been making a list of my fears that come to me in my dreams, and while I have intentional OBE's while awake, I request my soul to let go of the fear that I have. I try to go to the root cause of the fear, which is usually a traumatic event that happened in the past. I think the letting go while having OBE's is working, but I'm not 100% sure yet. I was also told that our dreams give us signs and symbols to keep us on the correct path towards fulfilling our destinies, and they also warn us when we're getting off path. I've had a few of those too.
