Question about a RPG type Lucid Dream

Hello everyone! I am new to these forums and haven't even really learned to lucid dream yet. I know some of the basics but that is about it. Now, I know that since I haven't learned to Lucid Dream yet, I probably won't be able to do this for a while, but I've just been really curious if you can do this. I've always wanted to get a letter from Hogwarts and shop in Diagon Alley and get my wand, then attend Hogwarts and go through all seven years, then get a job after graduation and maybe help fend off some dark wizard's from conquering the world. :P So is there a way that I could dream that and then pick up on the dream the next day where I keep all of my items and everything? Also, is there a way that I could have some dark wizard's rise to power, but even I don't know about them until later? Because I kind of want that to be a surprise as to who they are and stuff.

I've also wanted to go on my on Pokemon adventure as well but I'm assuming that these two things would work in basically the same way as you would just have to continue from where you left off. So in conclusion, would it be possible to do these things in a dream?

Thank you :)

Edit: (Forgot to add these questions also)

1. If I'm in class at Hogwarts, would learning the spells be easy or hard? And how would I make it so the professors know the spells to teach for each year?

2. Is it possible to read books in the library to learn spells, or just reading for fun? And with that could I also write letters (sent by Owl) and do homework?

3. Also, about how many days would go by per dream? (I don't know if it's different for everyone or what) And going along with time, would it be possible to have a Quidditch season during the months that it happens in the books?

4. Finally, would I have to keep track of house points or would my dream do that?

The dream(s) you wish you dream are higher level lucids, really.

Takes a lot of practice to get to the point of just being able to pick up story-lines intentionally.

1) It depends on your mind, and how difficult you want to make it. Can't answer the second part very well

2) Reading differs from person to person. Personally, in my lucid dreams I am able to read correctly, but not in my non-lucid dreams.

3) Depends. Chances are, it wont be very long unless you have a bunch of time skips inbetween, which would really reduce awareness (In my personal experience)

4) Well, not really able to answer this either. I don't think you can really dictate the dream that much. You could try writing them down when you get up. The end of each dream could be you running to the place where points are posted, and then waking up to write them down.

Ok thank you. I know that this would be very hard to do and I'd have to get really good at Lucid Dreaming but I was just urious if I could do this.

Thanks again :)

Sinister answered your questions very well, but I'd like to say that you should probably not try to control everything in you "RPG dream".
For example, don't try to dictate what spells the teachers will teach you; just go to class expecting them to teach you any spell !
Try to let the dream do its part, it will make the experience much more exiting !
