What a bizarre feeling! One of my goals I had in mind for the next time I had a lucid dream was to try and put my arm through the wall (not breaking the wall, just passing it through the solid object). I tried before a while ago when I was lucid, but didn't succeed. Last night I was nice and lucid, and managed to concentrate and tell myself "I'm dreaming, this wall isnt real." At first I was afraid I would hurt my hand if I tried to punch into the wall, but I punched it anyway, and it didn't hurt, in fact the wall kind of rippled when I did. That's what really convinced me I would be able to put my arm through, and then when I tried, it went through! It was like the wall turned into this soft jelly substance. It was cold and felt really bizarre! After my arm, I decided to go in all the way, and walked into it. Then I came out the other side of the wall, which was still in the same building I'd started in.

So anyway. I need to find out some other good stuff to try for next time ^_^
