I have some on and off periods when I can control my dreams.
The most amazing part of it is that I KNOW im dreaming..but im not *sure* im dreaming. Know what i mean? Many times I find myself back in my old high school... and I dont act on what I know is a dream because... im not sure! Talk about the power of social behaviour! wow!
There are a few techniques for "preparing" yourself to take control of your dreams before going to sleep. The one that seems to work for me is concentrating on a dream i've had before (preferably a recent one), replaying it on my mind and telling myself over and over (in my mind of course) that that Is THE dream.
Sounds freaky, but it does work for me. Chances are, if you concentrate enough and your brain "decides" to help and dream THAT dream that night, you will be able to do whatever you want.
My greatest success so far was beating the crap out of a kid I hated in school, hopping on one of the cars in the parking lot and doing 180's on the soccer field. Man just remembering that bring a FAT smile on me face! Woot!
If you are going to try it, I suggest you try to memorize a few rules:
1) Dont try to READ anything in your dreams. Reading is handled by the logical (conscious) part of your brain. When you are in a dream state, your logical side isnt working. Making it work will actually make the dream stop and possibly wake you up. Dont try to add things up or do math either. Just follow your impulses.
2) Do NOT go beyond the boundaries of what you know. If you know the area you are in (say, your high school), but you really dont know what was inside the house owned by the old lady in FRONT of the school, DONT go into that house. Your brain has no memory to draw upon and will trigger the logical part of your brain, ending the dream. This also applies for feelings, sensations (example: if you've never kissed someone..french kissing that is, and you kiss someone in a dream you take control of.. the dream will stop).
This is long enough, dont want to sound weird here, but this is what i know works for me and things I know NOT to do while in a lucid dream.
Im still trying to catch a dream of Aces High.. and fly the pork killing every damn red icon and reading "Victory 1000 by Tac; You shot Down Citabria"
