It wasn't really lucid. Oh, yeah, this is also my first post here. But this dream was strange. I was off doing whatever in a non-lucid dream. All of a sudden I hear the phrase "lucid dream" whispered in my ear 3 times. My dream jumps to an extremely vivid white field filled with red 3D cubes. Here I'm thinking... what the hell? It was so lifelike and vivid. But as soon as the scene jumped and as soon as it became vivid, I woke up.

I've never had an actual lucid dream, that's the closest I've gotten. Any tips or pointers as to why this would happen?
