It gets the visuals accurate, but the experience includes a lot of physical sensation that is very difficult to convey, e.g. the 'wind' that pushes you back and the discomfort of going into a chaotic dissociated state. You see those things but it feels very 'real'.

Wow, looks terrifying!

I can only speak for medically-administered intravenous Ketamine, but I would describe it as like relatively effortlessly floating inside of the non-physical space inside of you and meeting yourself in metaphor, all the while completely aware. The biggest risk seemed to be temporarily becoming a relatively inanimate part of the infrastructure there, and even that was a sort of pleasant and satisfying state.
