Here are a few lucid dreams I have had. And unlike virtual reality where you are just put into a programmed world and are limited to what that world does and unable to 'feel' anything, in lucid dreams you can be the exact definition of an all powerful god, think anything you want into existence.
The absolute most vivid one I ever had, and one of the first, I somehow just awoke within the dream. I was standing on the road I grew up at in my childhood. I was in awe how vivid and real everything looked and how awake and alert I was yet still in this dream. I was thinking how I would tell my father whom I've discussed lucid dreaming with when I would be awake for real. It did not last very long. I quickly tried to think of something fun to do while it lasted, so I said aloud I want a hot girl to appear. You can guess the rest.
Another....(I periodically will do reality checks, but I am bad at keeping up with that habit), I had a dream I was walking on a trail with gorgeous cascading waterfalls beside me. I was convinced it was real but I thought to myself that I should do a reality check to get back into that habit. I look at my watch, then look again and the numbers were completely changed. I was confused and did some more checks and was shocked I actually was dreaming. I decided to fly, like superman. At first I am flying slow along a shore, then I say that I'm in control so I want I should be flying super fast, suddenly I'm flying at supersonic speed. Then I notice the scenery is nothing special, and say I want to see amazing snow capped mountains. Suddenly I'm flying through the most beautiful mountains I had ever seen, and some having elaborate castles within them.
Another....I don't recall how I realized I was dreaming, but I was outdoors and it was night time. I said I want it to be daytime. Suddenly I see the sun rising (like in the truman show movie when they are looking for him), clouds moving as if somebody put a camera filming the sky for a day and has it playing on fast forward. Once the sun hits noon, time stops fast forwarding and is back to normal. Within 5 seconds it went from late at night to noon. I was also astonished how I did not imagine or think how to make it daytime, how I just say what I want to happen and it happens.
This is an interesting one. When I become lucid, I can summon people, either specific people or a type of person. I don't control what they say, and my interactions with them feel very real. I had thought it would be interesting to try to summon god, not knowing what I would see, or how it would be like. I can't consciously think of the great detail I see in my lucid dreams when I ask for things to happen. So the last time I had a really lucid moment, I tried to summon god. Nothing happened. Anything else I've ever tried, something will always happen. But nothing appeared and there was just silence. Deep down is it impossible for my mind to comprehend that? Or since I am in a sense god in my dreams, could I not summon myself? I will try it again though.
