From my experience vaporizing it, it's dosage dependent.

Breakthrough dosages could be considered NDE or OBE type experiences. You can feel like you've been transported to another dimension/hyperspace/giant underground dome made of light, and I personally see giant beings of light that feel very real and alive communicating to me through means other than language.

Sub-breakthrough dosages would be more similar to a mushroom trip though. Very intense visuals, serenity/calmness, increase in non-linear thought processes and psychomimetic (hallucinations of beings speaking to you are possible), and no OBE/NDE type effects.
