This is fascinating. I'm waiting for the time in my meditation practice when I start to notice it.
Could you (or anyone else who experiences individual moments) go into a bit more detail about what you experience? Do the moments tend to all be from the same sensory modality (e.g. vision), or are they mixed? If you can tell, does any moment combine more than one sensory modality? How often are there moments of thinking (e.g. narration or a visually imagined scenario), or does thinking tend to end the experience? How isolated do the moments feel: are they like isolated snapshots, or is it like a movie running slow where you can tell that there are frames but they partially blend together?
