Connecting with the inner worlds

In order to explore your own dream worlds you will have to bridge a few understandings and do some sort of minor work. One of the first things you can do is understand and contemplate that the plurality of dream worlds simply means that there's more than just one of them, like an oniric multiverse of sorts. Sometimes when dreaming you may come across places you've dreamt of already, and a plus for places you've never been to in meatspace. It doesn't take much effort. In fact you will find that the more you strain yourself the more you will only only find frustration as you try to force things. Do the following.

Inescapable for advanced dreaming introduction, the effect of the dream journal technique is to sharpen the mind for evolving in dreams. The working of interest here is the capacity of recollection after having the dream. Have a paper journal and a pen at the ready. After having woken up from an interesting dream, get to the journal quick and write everything down. It must be written down precisely and extensively. A cheaty technique for beginners is to write the directing plotline first, then underlying themes and secondary things, then as many minute details as possible. Do whatever is more fitting and efficient to you.

Of course it may be harder in the beginning as the writer feels the dream memory slip away from his mental grasp - and the reason for that is precisely because it's the beginning... you are straining an under-stimulated muscle. With more experience it will assuredly grow stronger.
The better dream recollection gets, the greater the lucidity while dreaming becomes. It is normal for everyone to have dreams every night, and that includes those who claim they don't dream at all. No, they've just forgotten that they've dreamt, and their dream lucidity is usually pretty low.
The real reason you need a journal is that it is physical storage which you can come back to and re-read. If you think you can just remember on the go and not write anything down then these thoughts will just swirl around in your brain and you'll remain stuck in your general space of mind. Successful physical journals are like treasures.

You are essentially raising your dream ability. If you think this is sounding like lucid dreaming preparation, you are right! Since it raises dreamability it is also pretty useful for lucidity, however that's not the goal. We'll need you to cultivate your inner narrative artist.

If you follow the journal technique correctly and raise dreamability but don't complete it with plotmaker techniques, you will probably just end up with memorable nonsense. You will need to shape that nonsense into a vibrant and meaningful something of a story.
To an extent, core of this success is just to become a good storyteller.

It would be pathetic to have to spoonfeed anyone in this, but just in case, all you really need is a medium of expression and to let the fantasy flow. I put creative writing but probably any form of creative expression that can hold storycrafting might do. Writing is just the real raw deal of it. Some people put any media by side and practice hypervisualisation meditation. While it certainly works, I am of the opinion that it doesn't produce just the right kind of artistic flow within the dream time.
Creative writing is really easy, until it isn't. As long as the writer puts no barrier on his flow then it just comes right out. Probably the worst thing to do is succumb to the retarded thinking that goes
"I have to produce something that lives up to a certain golden standard of creative writing!"

That's stupid. Because not only does it contradict the idea of creative writing, but also it does something really unhealthy for creative writing sessions: places a barrier.
Barriers usually kill it, unless the writer thrives off challenge and is thus perhaps already quite advanced. But for the novice the main result will just be the blank page syndrome.
The remedy to this is to open the floodgates and accept that what you will write will probably be garbage and that's alright. After all it's not like you'll show it to the president of writing who will invite all people around the world to come mock you about it in the street. Writings can always be burned or deleted, remember that and just throw it all up over the paper. Step four -- acceptance. It is because of this disinhibition that children often are effortless fantasy creators.

So you'll want to increase your creativity. This must go hand in hand with dream stabilization because otherwise, as stated, you will just have wild nonsensical dreams and they won't get you anywhere.
Both stability and creativity are severely inhibited if your sleep schedule is disturbed. At first it is recommended to go to sleep just a bit earlier than necessary in order to keep the mind awake when sleeping. While really boosting your dream capacity, it may rarely cause some sleep paralysis, which is completely benign and whose hallucinations cannot hurt you in any way.

What completes stability and creativity is something I've come to call Halling. It's the idea of the character of a dream, or its depth, its soul, its sense and themes, it's vibe. Its red thread, or its fate, or the mood of its story; whatever you wanna call it. It's what makes the dream not bland, not a very ingenious trip to the dentist or an story about how you tripped and fell in a bamboozling way. It's like the reason a video game's plot is good, that which grips you, its magic, that which is bigger than yourself, and which makes you feel a certain kind of way.

One dream experience I thought of when writing this was where I was in an empty train, sitting by a big unclear window through which the sun was shining golden rays. I looked outside and there was nothing but yellowish grass plains stretching so far, and a few industrial buildings somewhere. But the sun was the moment, it shone through that window, and that part of the dream was just that. I sat and looked, and the train went, and then the dream continued.

Maybe this helps with the understanding of the concept. In order to develop this sensibility, I can only suggest the following. Play more soulful videogames? I recommend Dishonored, Far cry 3 and Life is strange for starters. Watch enlightened movies, not hollywood filth and cultural derivates, you'll poison yourself. Try daydreaming more, and do some jouskas. Whether you want to practice more life-fulfilment and tie your personal blooming to the dream dimension is up to you ─ personally I'm the kind of person to go full Inception dream-addict mode and get lost within my own dreams, which is delightful. I would listen to an Alex Jones and Joe Rogan podcast where he's talking about how the elites are taking off with hyper-advanced technology and creating a break-off civilization, and my halled-up subconscious would think that's a cool idea to play with and spin me an interesting dream about me infiltrating the upper layers of a stratocratic archology, borrowing some ideas from Deus Ex Human Revolution. So essentially you must become better at dreamweaving, and when I mean you I mostly mean your subconscious. Using these techniques and then some the ideal outcome takes the shape of the subconscious weaving you a sub-world, hopefully with plot and scene, in which you, meaning the conscious part of you, evolves and performs actions within. It's really similar to a video game situation, where the subconscious corresponds to the game developer while you are the one to actually play it.

You and your subconscious will become artistic partners. You will find that as the consciousness, there are ways in which you can influence the ways the dreams are woven, typically their inspiration. You will feed your subconscious artistically inspiring material and watch the scene unfold in the flavour of the inspirations you put in.

And this is the art of dreamweaving. As for the creation of dream worlds... well, eventually along the dreamway, you will look at that journal again and put some things together. You may recognize places in your dreams, or feel like two dreams must have taken place in the same world. You will consume and input more inspiration material and while doing so suddenly think that something sounds really familiar to a certain strain of dream you've channeled. But most importantly, you will connect them within the realm of feeling ─ or the dream vibe.
Not just emotions, not just ways of thinking. As if the dream has taken on a personality or character of its own. You may find the core of such characters in certain complicated feelings, and think of your 'dream-map' as a heterogenous swelling of intermingling emotion-hotspots, and this sometimes even as you are awake.

And you may find that at some point, the dreams keep themselves going, and no longer require too much practice on your end. And also, something which is wonderful, you may recognize the existence of a `golden dreamzone` of sorts, which is when your sleep cycle is just right, your capacity is just great, and where you know that every night you will plunge back down into your own multiverse of dreams. Don't disrupt the golden dreamzone! It would be like doing a combo-breaker, and in this case you want to keep it going.

You may also find that as long as you've gone through the exercises correctly and stayed true to yourself, your dreamverse will be filled of subverses that may resemble your character and what you like. Usually Ideas you like to entertain, and dimensions of feeling that you've channeled. Now as is usual I get the feeling I just won't be truly understood when I talk about this at all.
