i just had a good idea. Ask someone to take you to ‘Lucid School’. Like Driving school, except you practice your lucidity and get beter. It will boost your moral, and will definitley be entertaining.
Quest suggestion
Prepare, and beat your fear. Idea from Python Angel’s dream. Diffrence was in quest before fighting with fear, you have to prepare to it. Get a sword, a gun, summon a ginat flame thowing duck, Find somebody who will can help you to beat it. Then ask for your biggest fear, and fight it.
wait a second, this one is hard, if something fails, there might be a fearful nightmare… 
hehehe, we don’t want to tramautize half of LD4all because of terrible nightmares =]
But that Idea gave me one! Find the Mirror of Erised (it shows your heart’s greatest desire,) and see what it shows you. Then go through it!
I believe magnus already suggested that one earlier 
The next Quest write up is a bit delayed, i hope to write it tomorrow, thank’s for your patience.
What abut finding the name of your dream world.
Ask a DC or someting: “What is the name of this world?”.
And then you have a name for youre dream world 
Yep, I suggested the mirror of Erised once but I never suggested to go trough it, nice idea Vi
I have a new suggestion, and hope noone has mentioned this before
Talk to a Wall
well, talk to anything that normally doesn’t talk and expect it to communicate with you and see what results you get.
you can talk to
Walls
Stones
Trees
Lakes
Toys
clouds and so on.
Ask someone to play your themesong as you enjoy yourself in Lucid World 
-or-
Go to a Lucid Mall, which has all kinds of Lucid Gadgets to help you do many diffrent things. There are items such as jetpacks, attach-on wings, Teleporting watch, a remote control that controls time, Lucid Cola, and MUCH more
Since pasQuale suggested it, I came up with a Quest idea!
Music! Turn on a stereo, put in your headphones, or teleport yourself to a live concert with your favourite band. Listen to the music, the lyrics, and see what kind of silly tricks your mind plays on you.
A task I’d love to complete ever since seeing Muse live. Music seems pretty rare in LDs as well.
On the topic of music, try to get your DCs to start singing with you as in a musical or a movie. I want to sing the songs from Corpse Bride with some DCs sometime 
More ideas:
- LEARN SOMETHING! I dunno if I have mentioned this already or not, but I believe it must be very interesting to try to learn something from a DC.
- Find your power animal(s).
- Give life to things that do not possess life. (NOT dead people/animals… I mean rocks, teddy bears, that sort of thing)
- Become an object. This can be mostly interesting, but maybe a bit boring, depending on the object. Become a rock! Too boring? Become a rolling stone
Whoaaaaaa AWESOME idea! I gotta try this!
Good idea with the Lucid School Wissam
I have a new ques suggestion
Find your Inner Child.
ince Painocus suggested to find the name of your dreamworld, I have a variation for that theme, ask a DC what your name is, and see if he/she answers your regular name or something unusual 
I have a new suggestion:
Merge with a DC.
So that
you + DC = one new person
This person will of course have all your memories(both the DC’s memories and your memorys)
but he/she will be a whole other person.
Suggestion: Finding hidden/lost parts of yourself
Not phisically, but something like attribute of personality or a dreams, lost by accidents or by time passing by. Could be materialized by feeling, a thing, or DC.
i didn’t have time to read through this thread but i’d suggest writing a story IRL where the main character does everything that you want to do in a LD, then when u get a LD put yourself in the story.
What about expanding things that you would normal have to get a microscope to look at (such as atoms) and seeing if their physical properties are any different than the models in science classes (if this makes any sense).
One thing that I’ve been planning on doing the next time I have a vivid LD is go on an epic quest to find a special music box. When you open it, it plays beautiful (hopefully original) music. I haven’t exactly thought up the specifics, but it should be an interesting expiriment.
Something I strive to do and think would be interesting would be to map out your mind as a physical place, be it a building, a city, or even a planet. Explore the Caves of the Subconscious or even take a literal trip down Memory Lane.
I just thought of a good idea. For all you music players - why don’t you play with your instruments and try to create music that becomes alive?
I’d like to see the results if someone tried those and normally doesnt play an instrument.
Find out what your Daemon looks like and it’s name.
For those who haven’t read Pullman’s books.
A Daemon is part of your soul, represented by a talking animal,
in most cases of the opposite sex.
While you are a child they daemon can change shape all the time but when you grow up it will lost the abilty to change and became one animal representing you for the rest of your life.
The Daemon is a really good one, I’d do that. In fact, I’ll probably do it even if it’s not a quest.
