Is Chögyal Namkhai Norbu correct when he says our life is unreal and that Buddha taught that life is just like a dream?

In this video clip you can see renowned Tibetan master Chögyal Namkhai Norbu saying that life is unreal and that the Buddha taught it is just like a dream. Is he correct? I've transcribed below: > Sometimes we have very nice dream. Fantastic dream... And we enjoy. We > are very happy. We are dreaming, for example... ...I'm looking and > someone is selling... lottery ticket. Very, very big lottery. I am > taking and buying from someone and I am returning home. And I am > seeing the television. And when I am looking at my number... The > television is saying that number! Then I feel very happy. "Oh, what do > I do now?" All this money. I am really happy and then I wake up. When > I wake up, I discovered that is a dream, unfortunately. I am not > happy. Or sometimes... very, very bad dream. There are many people > that want to kill me. They are arriving in my house. Then they are > starting to kill me. I feel very afraid. That moment I wake up. And I > discover, "Oh, that is only a dream!" I am very happy. **You see, good > or bad. Even good or bad. A dream is a dream. Unreal. So Buddha is > saying, our life is just like a dream. Big dream.** Dream of night is a > very small dream, but... Our life's dream, it has many day and night, > day and night etcetera. When we discover that... Dreams, we discover > when we wake up. But big dreams, we discover... When we are dying and > being in a state of Bardo (transitional state). Emphasis mine. A closely related question (with answers) is here.
