Interesting post indeed. Maybe the colourful moment was a moment in the future, and the dull/blurry moment in the past? If only a few minutes.

It's also possible this was a NDE as well, but doesn't necessarily have to be, I think that's hard to say. Besides, what would have caused the bruises other than the tightness of armbands?

Perhaps this was a "NNDE" almost near a NDE. Not sure if that even exists, but maybe it's an explanation for the experience you had.
