Most of the time a dream just like most people, but once in a while I experience being awake in a dream which I also call lucid dreaming. It's very interesting and the level of realism will vary. I find that it varies depending on how I have let my different desires (e.g. lust, hunger, laziness, etc) dictate my behavior during the day. The more control I exercise over them the better the experience is.

But I have also had a complete different kind of experience, one that is more realistic than lucid dreaming. It feels as real as being awake. I believe that this is what many call the astral. I can count the times I had such experiences with one hand. It's very rare for me and it requires such an effort that I fail most of the times. And by effort I mean not acting on the different desires that come during the day and trying to understand what triggers them and dismissing them without emotion.
