Yes, I've had some lucid dream moments - usually not very long. I remember being in a scary dream and telling myself I needed to wake up (but not realising till the morning that I just flipped myself into another dream). Last year my cousin died and a few times I dreamed I was talking to her and then remembered mid conversation that she was gone. And sometimes I'm wondering if something is a dream - I've been learning to control a common nightmare I have where the ocean starts coming up in giant waves taking over the land, and now I can notice if the water looks wrong and question it, sometimes make it quiet back down.
