My story! I am an Ex-Muslim, became and Atheist. I was visited by an Angel of God.

Probably your right! But how could i possibly stimulate the experience in my brain and create the image of an Angel if i never opened a bible in my life, I never knew who Daniel was, or read about angels. I began searching for the truth after I had the experience, and the only reference i can provide is found in the Bible. 

Your argument might be plausible if i read the bible Chapter 10 before i went to bed, and unconsciously my brain begins creating image or vision of an Angel. 

Post-hoc rationalization probably.
Are you saying you never had exposure to stories of supernatural creatures?
Are you consciously aware of all your past influences and able to judge between them which are in play at any given time?

There's lots of neural processing that goes on without our being aware of it.  Just yesterday, I was watching an episode of 'The Love Boat' in which Marion Ross and Ronnie Howard were playing the parts of Mrs. and Richie Cunningham.  There was a sit-com that spun off of this but I couldn't remember the name and gave up on it.  Fifteen minutes later its name, "Happy Days" just popped up in my mind.  Clearly, my brain was off working the problem without telling me anything other than the final answer.  Your mind works that way too.

The lack of detail in the biblical description of 'angel' also helps you in your preferred conclusion.  If it was more demanding, for example, if the bible gave a specific brand of sandal, and you observed the same in your sleep-paralysis experience, you'd have better evidence of a linkage of some kind.  As is, you're claiming more than your evidence supports over an alternative, non-supernatural explanation.

My view of the Angel was, His feet was like human, He was wearing a white garment, His face was shining, and had wings, I didn't see any eyes, mouth or nose. Finally, his color was almost sliver, or chrome.  I know that if i told this description to a sketch artist, he will think i am a lunatic and crazy, and they will probably send me to a mental institute.  But, i was shocked when i noticed that Daniel gives the same kind of description of the Angel. 

Its gotta be the truth.
