I have experienced the eighth dimension if not the tenth. I became everything, everywhere, at all times. I experienced egodeath through consciously meditating and letting go of this physical reality.
What I experienced was infinite peace and white light. It was truly the most incredible thing and my experience coincides with what people report from near death experiences.
I guess you were high, that's why you defied it

okay, now let's get real
spritual?
it's all in your brain, you didn't defy gravitiy

Everything is in your brain, your mind manifests your reality through different frequencies such as light and sound waves.
