I would like to share my 2 cents on it, but I thought it belongs to Philosophical Thoughts thread and didnt want to interrupt Sammy’s and Dr.Manhattan’s discussion, so here I go:
I would like to turn around what Sam said a bit, and say that (IMO) everything anyone experiences is real.
Especially with lucid dreams, perhaps also when one is very, very good at visualization(I have never got to that level, so I can’t confirm) when you are proficient at lucid dreams, then you eating a pizza in a lucid dream feels almost, if not exactly as it feels when you are eating a pizza IRL.
The experience can be almost identical, so from the “spirit” or consciouseness perspective ( wont go into definitions, I mean the part of us that reincarnates) it is as real, as if it was experienced in a physical plane.
If we incarnate to experience different things and learn from it, then LD can be a method of speedrunning this learning.
Think about it: no matter how much possibilities you have, there are still experiences you would have to reincarnate to experience.
Some of experiences would even be impossible to experience on earth, no matter how many times you incarnated here.
With lucid dreams you can experience many of such things, and there is no need to incarnate again for those specific experiences.
Of course, they wouldn’t be identical, but very, very similiar. Kind of like Conceptual Realizations field.
I also wanted to adress something from another of Sammy’s posts:
I realized that our definitions of perfection were quite different.
I think I understood how you see perfection and understanding that broadened my perspecitve a bit.
“Your” perfection is a moving one, right? Perfection that is constantly growing and changing.
Like a tree being perfect in every stage of its growth, or more precisely seed being perfect at being seed, sapling being perfect at being sapling etc.
“My” perfection was (now I have two, after understanding Your POV) an unchangfing one.
not moving and not growing.
Why? Because its already at the pinnacle of growth, its already as evolved as it could get. Its already “The highest” so any change in it would mean its no longer perfect.
Using the tree analogy, it would be the moment of tree’s exsitence when its most developed, but not “old” yet.
Its age isn’t doing it “harm”, its neither too young or too old.
And to adress what You said about heaven:
Eternity in perfection couldn’t be boring right?
Boredom isn’t perfect.
Praying to God and all of this stuff aside, of course. It would bore me too 
I wish I could exist in this unmoving perfection though 
That I would’t need to “change” anything.
To not have to perform any action or “growth”.Maybe thats the extense of my laziness lol.
Also, if it was perfect, where did the need to expand and grow came from?
How is even growth and expansion possible, when initial state is perfection?
And I don’t say that because Im unhappy with my life. In fact I think Im most happy I have ever been.
Maybe I was overdramatic when I said :
What I meant is, that this necessity to grow and learn feels like a chore. But not Sisiphus kind of chore.
Like a boring homework. Perhaps thats why perspective of speedrunning it feels so appealing to me.
Writing that I realized another thing, it blew my mind a little when I saw this, must be Conceptual Realizations kicking in.
“Your” perfection is
“My” perfection was
So, what kind of perfection will be?
