Dream - Composed of bright particles

A long time ago, perhaps in the mid 1980's, I had a dream in which I was composed of bright particles and rose up from my sleeping body to form a peak, like the ridge of a wave, and then sank back down into my body and spread out to the sides, and then drew back into my body until I was within it, at which point I woke up. I did not find it scary, just interesting. (Some other experiences WERE scary, though.)
