If you smoke it, you will appear to pass out for several minutes, where you'll have euphoric insights into other dimensions.
A DMT trip literally transports you to another reality. Users report access to a completely different plane of consciousness.
Spirits, aliens, even elves and other strange creatures are encountered in worlds that users report seem to be inhabited by other-worldly foreign intelligence.
If you really want to have an experience like that and explore the depths of your spirit you need a guide like "DMT: The Spirit Molecule- Near-death and Mystical Experiences" by Albert Piaget.

Psychedelic Drugs: how science and society see them
the Pineal Gland
getting DMT: feelings and thinking
mystical states, dying and unseen worlds
the future of Psychedelic research
...and much more
