Ooooh I love this dream!! It really made me laugh too - dreams are insane eh?!
So...this is kind of interesting because I just posted a post on the Consciousness Forum about brain surgery/frontal lobe dreams - so I've linked that below in case you want to check it out.
Okay....I am not quite sure what this dream is about so I'll start with the number that really stood out:
1: Individual Self: independence, your uniqueness, your strength, your Conscious Mind.
3: Committment to integrating all three aspects of yourself (mind, body, spirit; subconscious, conscious, super-conscious) 3 is also about Expression and expressing yourself - communicating your truth.
5: Change and Adventure in your physical world.
0: Divine energy: cosmic help.
So....according to the number it looks like in order for you to strengthen your Self (1) you need to Change (5) and integrate your Higher Self/Super-Conscious Self into your Conscious and Subconscious Selves in order to be able to fully express yourself.
Hmmm...sorry this is so rambling!
It seems funny that the brain surgery was not needed. I wonder what part of yourself thinks that you need to change your thoughts? Or are you wanting to 'improve' your Mind - but the people around you don't understand? It almost sounds as though you are taking responsibility (your insurance won't pay for it) for improving your Mind, Thoughts, Consciousness...but that it is a painful process for some reason.
I wonder if you are an Air sign or have an Air mercury? hmmmmm. Would love to hear what you think this dream means - it feels pretty important...
