Hello I just registered today and had a few questions for you guys. I have only had a few lucid dreams all fairly recent. The experiences evoked several questions in regards to the range of possibilities while dreaming.

1) Is it possible to turn yourself into an animal?
2) Is it possible to split your body in half? kinda like a starfish
3)Lets say you become lucid and proceeded to commit suicide (like you shot yourself in the head) what would happen?
4)On a similar note can you become lucid only to go to sleep agian? A dream within a dream? (inception style?)

All of my experiences consisted of partying with my friends, flying, and trying to control light. I have heard from several sources that it's not possible to control light. On one occasion I plugged in a lamp and it lit up a whole room, very bright mind you. I think that's it, any answers are very appreciated.
