First off this was a DREAM usually dreams form from what we have experienced during the day in metaphors. Let's look at this in more detail.
Was there anything blue, white in your day?
Did something become clear to you in your day?
Tall female in your day? etc etc etc..
As you go on it becomes clear this was a 'sexual' experience which are common when the body has been 'derived' of sex for some time. This is a way the body releases 'pent' up tension.. through sexual dream experiences, which are all too real and orgasmic.
Neuroscientist discovered there is a bit in the brain responsible for 'religious' thoughts. This area can be stimulated artificially and can give a person a 'spriritual' experience. For example: those who suffer siezures often describe 'spritirual experiences' it is thought Mohammed in Islamic faith was epileptic, therefore experienced this and believed he was a prophet. The same effect can be produced 'artificially'.. Also interesting is the above the body experience, we've all heard the testimonies of those who experiences this when 'technically' died for a few moments in the operating theatre. You don't need to die to experience this, but just have that bit of the brain stimulated to experience it..
Your experience as described above is
1. a dream - usually metaphors for what we see, think, desire.
2. a sexual experiences - the calming the day after is the release of pent up sexual energy.
3. you interpreted it as a spiritual experience..
That's it in a nutshell.
There is much online about neuroscience and religion and why people interpret experience to be spiritual.. also interesting sex in dreams... to explore this further if you're interested in understanding your dream.
Edit: if you are 'religious' the blue and white could symbolise what they respresent to you and in conflict: ie: blue=pornograph and white=spirit.
I've copied and pasted this as is interesting dream/sex stuff:
"The mind has something called a 'dream censor', which tends to 'clean up' dreams.
So, if a person who has a very strict puritanical outlook starts to have a sexy dream, their dream censor may alter that dream so that very 'rude' things are replaced by symbols.
Thus, a man of strict sexual morals may have a deep, unconscious desire to have sex with beautiful women. Instead of dreaming about vaginas, he will keep dreaming about tunnels and subways. Instead of dreaming about breasts he will dream about pleasant hillocks and mounds - and so on.
Similarly, a woman whose sexual morality is very strict won't dream of penises. Instead, she'll dream of penile symbols, like:
* church spires
* rockets
* cigars
* tall chimneys.
However, in our experience, this kind of 'dream symbolism' seems to be less common than it used to be. People are less 'hung up' than they were a generation or so ago - which is why they tend to dream about explicit sex, rather than symbols"...
