Paradise or something like that, a place where there's no hatred, no pain, no suffering, and you don't have a physical body as such that has needs and even feels pleasure as a need (pleasure doesn't seem like a need to me).
Honestly, I had particular sensations when I was taking antidepressants, clonazepam, and I was in a very particular state that generated a certain peace, as if I didn't need anything, not even thinking about death, or living, or achieving anything... It was strange, but more or less like that, but x100% would be ideal for me, since otherwise, existing again, even if I were a millionaire or "powerful," would be hell in this world.
