Do not fret. Now that you know what your doing, there's an easy way to get out of universe LD.
Realize that all the rules you've ever learned about lucid dreaming (can't have sex too long, they don't last long at all, etc), only apply to universe LD.
Now realize that there are an infinite number of other universes in your mind. Here's some examples:
- The Matrix Universe
- LOTR Universe
- Harry Potter Universe
- "Real Life" Universe
- Anime Universe
- etc
Each of these Universes already exist. All you have to do is find a way to enter them (a portal).
"Portals" can be anything. You could jump through a mirror, or tear open a rift in time and space, perhaps you could just kill yourself and resurrect in whatever universe you please.
How To View These Universes:
Don't see them as extensions of your lucid dreams.
They are full fledged universes all on there own. Just like every
normal dream you have is a full fledged universe of its own.
They have their own laws, their own geography, their own everything. Your not creating anything.
You don't even have to worry about them ending because of something you did. Universes don't just end, thats illogical.
Of course, REM limits the amount of time you can stay in a universe. Just as the need to sleep limits the amount of time you can stay in real life.
Don't worry about how long your REM period is going to last (how long you have until you have to go to sleep), just dwell in the moment and calmly do whatever you want.
Think of the reality your in right now.
Real life is solid; its fundamental laws don't just change.
Lets say I'm walking down a hallway in real life and I see a "hump" on my couch as I walk past the doorway. Do I suddenly run in terror thinking that that hump is a massive spider thats about to attack and slay me?
Fuck no.
I would try to reason away the hump:
- My doors are locked so it can't be a robber
- This is real life so its nothing supernatural
- I'm the only person in the house
- I have no animals
- It has to be a wad of clothes that someone threw on the couch without folding
You see, I did a check with the rules that were established in my current reality to logically see what the "thing" was.
You do the same thing in the universes that you visit in your lucid dreams.
In "lucid dream universe", that hump could literally have been anything. The rules said there were no rules.
If I had been having a normal dream about how all the women in the world wanted to sex me up, that hump would have been a sexy woman.
If I was in a lucid dream and in "real life universe", that hump was just a wad of clothes.
Take the facts of the universes you enter: the laws, and build your expectations around that.
