Neither. You are already existence itself. Must you really prove to yourself that you are looking upon yourself aka looking upon the universe? You are conscious existence and being here in the “material” 3D world is your purpose. Your soul wouldn’t have manifested here if it did not see the need to. (Really, the point of having a body is to spiritually powerlevel because it becomes hard for you in the next life, I.e: having a body is easy mode)
If you’re just trying to figure out where (You) as a person “fit” in this 3D world, look no further than into yourself. Meditation. Know thy self. The key word being “SELF”. Astral projecting and/lucid dreaming are cute but that isn’t inside of you.
Your existence is here, on earth, in your body (probably somewhere in the area of your spleen).
Controlling your dreams (lucid dreaming) or projecting yourself somewhere Outside of your body will not lead to any discoveries you are trying to find. It’s all inside. Just meditate. It will come to you
(And if I missed the point ENTIRELY I apologize XD)
