Pain to prove I'm dreaming... just once, I pinched myself just like the old saying. I felt it just like pinching myself in real life and I didn't wake up. But I knew I as dreaming already, and just wanted to test that old saying out.
I have an ongoing, bizarre lucid dream goal that I tried twice:
I want to rip my own arm off in a dream!
The two times that I tried it, it was stuck on there pretty good and it didn't work.
But a few weeks ago, to build up practice, and start small, I decided to rip my own finger off. It worked. It stretched and broke off like play-dough. There was no pain. Then I looked and noticed, I still had 5 fingers despite the one that was missing. Somehow one just appeared without me realizing it. I tried again, and still had 5 fingers, with two missing. The palm was getting wider to accommodate for the extra space. I then went crazy and used my other hand like a knife, and chopped off many fingers, karate style, and now the palm was about a foot long and I STILL HAD 5 FINGERS at the end of all the missing ones. I never actually held the missing finger in my other hand and looked at it. I should have done that.
It sounds crazy, but an LD goal of mine is to rip off my left arm with my right one and hold it, and look at it. Maybe even bite into it and see what it tastes like.
I have a feeling my left arm will still be there when I move it, and will probably be holding a dead arm with both my hands, like I just created a new object in the dream. Then again, I really don't know, so that's why I have to try it one day!
If we all lucid dreamed this world would be a better place.
