I got lucid in an afternoon nap today.. unfortunately I've forgotten some of it - it was quite long, maybe my longest lucid ever, but because it was so long I only remember certain things... also I think I may have gone in and out of lucidity a few times. However, one bit I remember quite clearly.

I was lucid, and walking around a sort of town square, thinking about different things to do, when I remembered reading about morality in lucid dreams, and certain experimenters trying hurting themselves or others. I decided to try an experiment. There were lots of dream characters about, so I decided to try to "cut" one. Killing them never occurred to me, but I somehow got a razor blade and approached one. He just stood there, and I took my razor and made a cut on his arm. I saw the skin open up but it didn't bleed much. It was strange though, he just...stood there. I felt kind of bad, but also a bit baffled by his reaction, so I went up to another DC and did the same thing. He put his hand over the cut like it hurt, but didn't say anything... and then I noticed that I really felt quite awful - bad and almost a little sick and disgusted, and also quite guilty. I knew the whole time that I was in a dream and this wasn't real, but it didn't seem to make much difference. I felt I couldn't leave them like that. I remembered reading about lucid dream healing, and so I rubbed my hands together til they felt warm and had a sort of vague yellowish glow to them, and I pressed them against the first guy's cut, closed my eyes, and thought "heal". After a few moments, I got the feeling that he was healed, took my hands away, and the cut was gone. I felt relieved, and I did the same to the second guy, and they both looked really grateful, and I felt much better. I've come to the conclusion that I can't hurt anyone in a dream - I felt just as bad about it as I would in real life.

Has anyone else performed an experiment like this - if so, what were your results?
