Just today I had what I called "Parallel universe dream" Where It's me but I look different and my surrounding is different. The more distant the universe, the more things will change and only general lines will be similar (an example of general lines: let's say you have a landmark near your house, you will also have a landmark in a distant universe but it will be different, meaning it will occupy the position of the original landmark, in reality close to your original reality, the landmark will look like what you know and only small stuff may change)
I like visiting Parallel universes where the reality is better from here, sometimes is so fare that We are in the same parallel linear time point but the date is different, like instead of 2022 it's was 2022 and they had more minutes (could be possible with different division and earth rotation and stuff.
I guess the more clsoe to you reality the more chance it will happen to you in reality.
Idk if I should tell you my recent dream because it will take time
Oh and usually Parallel universe dreams feel very vivid and only less vivid in hindsight.
Also It's related to soul and spirit stuff but it's too hard to me explain it in writing and in English.
