I have used a broomstick to fly before. Now I don't need it, but it sort of acted like training wheels.

Since all dream control is based on your belief/intent, these ideas are useful but ultimately crutches. Using something like a wand to preform magic is helpful because it lets you practice and experience what is possible; but once you know what is possible, you can leave out the wand and just intend for something to happen and it will.

That can be easier said than done, however. I still use something like your transporter to move into different dream scenes as I can't just manifest one instantly yet.
