I have had many similar experiences.
I was once talking to a DC, when 'boom' everything became extremely vivid (almost to the point of it being uncomfortable and more realistic than reality) I began staring at the creases on the DCs face and was astonished at how intricate everything was, yet I was in my own mind.
I'd strogly suggest taking time to simply experience an LD, it can be more exhilirating than flying or --------- (insert dream action here )
