In my experience with Lucid Dreams, once I had them regularly,
it seemed as if I started out with an empty toolbox,
that fills itself with tricks, tools, skills and other usefull stuff as I had more regular LD's.
Like in a Zelda adventure, where you start out with some leggings and a wooden sword.
Once a technique seemed to work for me, it was as if these techniques would be
readily available on subsequent lucid adventures.

Most of mine aren't so unique, and I've lost the LD skill (pickin it up again)
so I'm interested to hear what you guys have going on!

-Reality-Checks; like backwards summersaults, swinging an arm through another, or quick turn of the head
-Changing scenery by creating doors and stepping through them
-Asking friendly dream creatures to meet me again the next night, or helping me 'awake'
-Transforming objects in my hand (into bottles of beer or spliffs :)

I've also read that it's possible to create a home in the 'astral', that will then always be there for your return.
That you can create doors in your home that lead to specific other astral places, and other cool stuff,
but I've never gotten that far (yet)...

Do you have an astral apartment, or unique tools, and tricks up your sleeve in the lucid dream world?
