I don’t smell but there is sound and feeling, and the visual experience is generally very realistic like if I were going about my day to day life, I can imagine fine but the visualizations in my dreams are often like ray tracing on ultra graphics. One that especially comes to mind, I dreamt I was in a dog fight and doing a bombing run in a space ship, and I looked behind me and watched each bomb explode in vivid detail one after the other. It was like better detail than in a movie in a way.
