My LDs lately get VERY vivid and stable , without any sureal additions from my beloved enemy, my subconsious - and that makes me afraid of doing some things:
LAST NIGHT’S EXAMPLE:
… I am in my dad’s house, fully lucid, and all my senses work 100% well. A very vivid dream, just like old times. I reach the open window (of 6th floor), and I sit on the ledge with my 2 legs hanging over the void. Mind that I am not afraid of heights or anything. At that point, I am afraid to jump and fly. I thought to myself : ‘wait. this is way too real. however, the RC worked. it IS a dream. yes, but what if i am crazy and this is the waking life? I will die??’ And I dind’t jump, WITHOUT LOSING LUCIDITY . That lead me to a FA.
New fruits for Alex C. Until now I had poor LDs and now that I have quality on my plate, I think I am crazy inside the dream…
Alex that is most funny , at least you have vivid stable LD’s now… . Anyway I guess you should just continue and from experience learn to convince yourself more and more in the dream that you can actually do anything without being hurt (you could use autosuggestion for this!). To me it sounds like your level of lucidity (awareness) could use a little boost to get to this point.
Instead of doing things that will hurt you, you could try doing things that you can only do in dreams. Taking your example, instead of jumping out of the window you can jump up into flight and fly out of the window. Or you can morph your surroundings so that there is no ground to fall on when you look out of the window.
Think about it this way. In the waking world there are certain rules. In the dream world there are certain rules. If you don’t do something in the dream world because you think you might be crazy then what what makes you so sure that you know what the rules of waking life are?
My suggestion: trust yourself. If what you believe is not true then you will never know unless you test it.
Also if you truely crazy inside the dream and what i have suggested doesn’t work you could try to use that craziness. Make yourself believe that you are just having another crazy dream and in that dream you can do anything you like. I don’t know if i’m making much sense here but it might help.
