Buddhism and science are both models of reality. Since reality is ineffable, no model is definitive. However, the finger of science is firmly pointed towards this dream experience. Buddhism is also largely pointed towards this dream experience, but because of Dzogchen, we also have a finger pointing towards the nature of reality. Dzogchen also has plenty of models, but that is not what is important about it. Although I believe that glimpses of rigpa are actually somewhat common, both in eveyone's life as well as in all cultures, as far as I can tell Dzogchen is the only "model" that notices what it is and says "pay attention to this!" Its like in a dream where all kinds of dream characters are running around making claims about how stuff happens in the dream, like "after extensive experimentation, I have determined that if, when my grandmother turns into a bus, I whistle Dixie, then a butterfly flaps its wings in the Amazon" etc. But then, one dream character says "hang on, this is a freaking dream! Now, notice what is the groundless ground of this dream and any possible dream!" All of Buddhism is supposed to do that, but a lot of the Buddhist tradition got caught up in the dream particulars after all. Even a lot of Dzogchen got caught up, but still there is that call to wake up and smell the rigpa, and the transmission of the knowledge of what that means and what it looks like.
Thoroughly tame your own mind.
This is (possibly) the teaching of Buddha.
"I must finally conclude that this proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind."
- Descartes, 2nd Meditation 25
