Some are very real, my last were I was floating just above an asphault road and I asked a dream character what it was like to be a dream character was very real. I was floating so close to the surface of the road, I could feel by skin brush against it occationally.

Others are very poor. In a LD I had back in Jan. I had almost no visual, almost all I could see was just a green blur, and dream spinning did not help much.
