in my lucid dreams i want to get somewere i picture the place in my mind try to teleport ive tried opening doors… what should i do…i really want to get to this place… 
I moved this to first steps from stuff of dreams, since it was about using “powers” in LDs.
The only thing you need is the self-confidence to know that you can do it.
Remember … all sorts of weird stuff happens in normal dreams everynight. You have the power when LDing to control what happens … anything is possible.

welcome to LD4all
Did you try walking through a mirror or spinning? It’s probably not working because you don’t truly beleive that the other place will be on the other side of the door. Next LD try to really convince yourself that the other world is on the other side.
Wow, you already had a LD? Impressive…
Btw is your name really Sora?
Or did you get that from the game?
I agree with Tcc and moogle, you really need to be confident and believe that it will work. If you don’t really believe then your mind will simulate what happens IRL, and the place won’t be there. Remember, everything is possible in a dream so really try to believe. 
Also, your mind may be more content with using devices in the dream to achieve some effect, because this is more like what happens IRL so you can kind of trick your brain to get the effect. If you can’t get there simply be opening the door, try creating a teleport machine or some other device. Once you have a helping device in the dream, you can use it and it may give a greater success than without.
So the two points of advice are:
- be confident
- if you can’t get there by opening a door or something, find a teleporting machine or other device to help
I hope this helps
What about flying or driving? If you haven’t quite mastered teleportation to a specific location, travel there by other means. Fly if you can, drive the distance.
Use a method that would seem a normal way to travel there.
