A man in a counselors office has experienced hallucinations and is brought in one by the helpful doc. We get to see his trip. And don't let the annoying intro scene with the fly put you off, the visuals are great once the trip starts.

The soundtrack is Divine Moments of Truth by Shpongle, the track is inspired by the consumption of DMT. It is a musical impression of a DMT trip. The first letter of the words in Divine Moments of Truth themselves form DMT.

DMT is a short acting very high intensity trip. Users can experience ego-death. Which is the state in which there is no I anymore, you don't know who you are, what you are, you just know that you are. You are completely lost in your location, your room is no longer there. What you're looking at could be any strange hallucination your brain brings up. There many people who see very intricate geometric patterns everywhere. Some people report machine like elves which play with you.

If you want to know more about what DMT is visit Erowid:
It has all the facts about the drug and a database where people write trip reports, it can give you a good impression on what it is like.
