So the other night I had a dream where I cut my finger with a knife. I looked at the cut. It was small. For some odd reason I wonder what my Finger would look like short, so i decided to cut it off about mid way (it was my pointer finger)… And did it. I was not lucid and It was a strange but interesting experience. Has anyone ever had this happen?
Moved from Lucid Adventures since it’s not about doing something while lucid 
I’ve cut off my own finger as an eager sacrifice to a dead prince demi-god, or something… It is a strange feeling, the absence of limb.
Something that used to happened fairly often was that I would lose my teeth. When I wake up, there is a brief moment where i feel nothing in my mouth, then spontaneously i start getting the feeling back, as though they are popping out of nowhere.
It’s interesting sometimes to experience how something like this would feel, or the view your brain would have in such a case.
The last dream I recall not being in one piece was when I asked a friend a question and his answer was to blow myself up, so I focused condensing my energy within until bang, I exploded. I remember looking up at him only being able to feel my head and afew other limbs in different locations. My friend looked down somewhat concerned, yet surprised that I actually listened to his sarcastic remark as I lay there feeling drained. 
I had my left buttcheek get cut off by a samurai ninja. Felt uncomfortable.

I have sacrificed my right arm due to some rite of passage.
