The level of detail is just insane. I once stopped to examine a flower and it was as detailed as real life. I ate sushi and other foods in a dream and it was literally the best tasting sushi I (n)ever ate. I could also give myself super powers like stopping time, flying, elemental manipulation, etc.
It's ridiculous how much power there is still to be harnessed.
I've been thinking about this problem from the other angle. When we lucid dream there is a certain part of the brain that is deactivated that otherwise makes us aware that we are not in the real world.
That is, in the real world we don't really need to perform the reality check, we can tell intuitively. In the dream world this intuition is lost. I don't remember which part of the brain is involved but it has identified by comparing activity during normal dreams and lucid dreams.
If we could stimulate the brain in the right spot the right way we could inhibit that part that knows what's real and what's not and maintain full continuous presence in VR.
Note the study itself is limited to under 20s but shows a clear age-related decline.
My own anecdotal experience (which I agree, was awesome) confirms that.
Fun little book, but firmly a pulp: the lucid dreaming scene is really raunchy.
 Edit: Maybe Poul Anderson. It’s been a while.
Besides simply searching on google for how to lucid dream, do you have any specifics on the various methods and/or any tips on how to get started?
As a quick start however:
1. Keep a dream journal and write down dreams as soon as you wake up, as much as you remember. You will get better at this over time.
2. Perform reality checks. Count your fingers or blow air out your nose periodically.
However, there is a much more powerful concept called All Day Awareness. It is the notion that reality has a surprising amount of detail but we are just not aware of it during the day to day. So, just stay where you are and observe the environment. Look at things, hold them up close to your eyes. For example, take a leaf or piece of paper or your hand and see all the individual details. Fully be aware. This helps you understand when you're in a dream and so you'll be lucid.
3. Each night, say you'll lucid dream. It will work with enough practice such that you do lucid dream. It's not guaranteed however. This technique is called MILD, or mnemonic induced lucid dream. There are others.
Note: using substances like alcohol and marijuana especially will kill your lucid dreaming attempts as they inhibit REM sleep, especially weed.
Once you're in the habit of doing that, you'll start doing it in dreams, too. And in dreams, you're very likely to realize things aren't real, and that you are, indeed, dreaming.
That's the technique that works best for me.
It definitely matters because it implies we are consciously aware of ourselves during lucid dreaming but we’re asleep!. The memory of the dream is the only part that’s fragile. It’s another blow to the view that brain activity during REM is just randomly firing neurons rather than a creation of our consciousness.
⇒ If it was sunconscious, it did not stay that way.
Also, it would have been quite the subconscious. One of the participants decoded questions posed in Morse, and questions included simple math (“Then we presented a spoken math problem: 8 minus 6. Within 3 s, he responded with two left-right eye movements (LRLR) to signal the correct answer 2. The math problem was then repeated, and he again produced the correct answer”)
