Hey everyone,
I was wondering if you could planify your dreams before going to sleep?
For example, if I decided to have a really complicated adventure and wanted to have an already planned order like this:
Hello Tiantian
It’s generally a good idea to plan out what you want to do in your LD the night before otherwise chances are you’ll end up at a loss of what to do (happened to me on several occasions). You can plan it out in or out of bed. You just have to remain focused on your intent before the LD during say WILD or MILD or whatever technique you use.
Providing you can have a long enough LD with enough focus, you can theoretically make it as complex as you wish providing of course you can remember what you planned previously that is. 
Remembering stuff in a (lucid) dream is much harder than in waking life (due to some chemicals in your bream). This means that it’s easy not to remember the stuff you wanted to do, once you’re actually in a LD. To prevent this you must really clearly visualize in detail what you want to do in your LD before going bed or you’ll just end up doing stuff you didn’t intend to.
Yes, of course! It is very easy and effective! It will take time, though it does pay off in the end! I am currently doing something right now that requires me to do that (as well as think of a mantra before bed), and it has helped me become lucid since I started. I haven’t had luck with the incubation of the actual dream, though. I still have to reach that.
Just think of it throughout the day, especially if you are alone. You can take advantage of the loneliness to incubate your dreams! You just think about the scene for a bit. I wouldn’t think of a full-blown dream, but rather, the start of it, then becoming lucid, then what you will do. Let’s use a concert scene as our example. You feel the other people around you, the heat of them, you feel them pressing against you; it’s a wonderful song they’re playing; your favorite, in fact! Then you realize you are dreaming, and you complete your goals.
It may seem simple and easy to jump into, but in truth, it takes time. Just take advantage of your loneliness, and have fun with it. Feel free to ask more questions if you have them.
All right I see, thank you for your answers. Now I wanted to ask, how far is the limit of a dream? For example, is it possible to imagine one’s self as a character from a book and to live his adventures? or is it too complicated to be applied?
YOU are the limit 
if you think it’ll work, it will
(I take that back, there are a few things you simply can’t do, such as taking something from the dream world and bringing it to real life…)
Sadly this is so true…
I remember when I was young(er) and really tried a few times; I was perhaps not surprised, but I was nevertheless sad when it failed to work again and again (still am 
) 
I plan IN my dreams, that is when I am dreaming, I plan on the spot.
If only I had the in-dream attention span to do so 
If I don’t plan beforehand, my LD’s are pretty short and pointless. I dont’t actually plan out every aspect of the dream, but I set goals of what I want to do in my next LD. Having a purpose seems to help my mind stay focused on the dream preventing me from prematurely waking up.
