From within your own head, there is no real difference – your consciousness is presented with images or sounds or whatever that, while you’re experiencing them, seem real. It’s only when you wake up that you can look back and think “you know, it doesn’t really make sense that everything changed when I turned around, and that fish turned into a monkey”.

This; a dream can seem very real, but a few seconds awake and it becomes obvious that it was a pale imitation.

Although one time I got my leg burned by a lightsaber, and it hurt for a full ten seconds after I woke up. No explanation on that one.
