Level 1
This level produces a mild 'stoning' effect, with some visual enhancement (i.e. brighter colours). Some short term memory anomalies. Left/right brain communication changes causing music to sound 'wider'. Can be achieved with common doses of cannabis and MDMA, light doses of MDA, and light doses of psilocybin mushrooms.
Level 2
Bright colours and visuals (i.e. things start to move and breathe). Some 2-dimensional patterns become apparent upon shutting eyes. Confused or reminiscent thoughts. Change in short term memory leads to continual distractive thought patterns. Vast increase in abstract thought becomes apparent as the natural brain filter is bypassed. Can be achieved with strong doses of cannabis, light doses of LSD, light to common doses of psilocybin mushrooms, light to common doses of peyote, strong to heavy doses of MDMA, and common doses of MDA and 2C-B.
Level 3
Very obvious visuals, everything looks curved and warped, patterns and kaleidoscopes seen on walls and faces. Some mild hallucinations such as rivers flowing in wood grain or 'mother of pearl' surfaces. Closed-eye hallucinations become 3-dimensional. There is some confusing of the senses (synesthesia). Time distortions and 'moments of eternity'. Movement at times becomes extremely difficult (too much effort required). Can be achieved with common doses of LSD, psilocybin mushrooms, peyote, and ayahuasca.
Level 4
Strong hallucinations, i.e. objects morphing into other objects. Destruction or multiple splittings of the ego. Things start talking to you or you find that you are feeling contradictory things simultaneously. Some loss of reality. Time becomes meaningless. Out-of-body experiences and ESP type phenomena. Blending of the senses. Can be achieved with strong doses of LSD, strong doses of psilocybin mushrooms, strong to heavy doses of peyote, and common to strong doses of ayahuasca.
Level 5
Of the classical psychedelics, only DMT and very high doses of psilocybin are considered to be able to induce level 5 effects, however ketamine and Salvia divinorum, whose effects can be considered atypically psychedelic, can induce experiences of comparable intensity to those level 5 experiences triggered by traditional psychedelics. Experiences include total loss of visual connection with reality, the sense of not being human or having a body, and the feeling of being in many places at the same time. The loss of reality is so extreme that it becomes ineffable. People have been reported seeing themselves in entirely different settings than their original setting, and many people experience the feeling of being in a simulated reality. Religious phenomenon is reported at this level; often mentioned is a connection to an "all-knowing presence" or a "universal knowledge", which many equate with extra-terrestrials, artificial intelligence, God, love, or "enlightenment". Users commonly report:
1) Being clearly thrust into outer-space at extreme speed.
2) Being thrust into an expansive void-like alternate dimension consisting of bright colorful fast moving kaleidoscopic environments, dynamic pulsating colored beams, as well as complex three-dimensional geometric, mathematical, and linguistic patterns made of light.
3) Continually traveling at great speeds, while watching patterns fly by morph, open, and reveal more complex patterns within.
4) Encountering different types of living beings and superintelligent body-less entities at the same time as 1, 2, and 3. These reports include contact with free-floating entities made of light resembling giant spheres, humanoids, multiple types of unrecognizable insects, human-sized praying mantises, elves, cephalopods, complex robotic machines, and plants.
5) Intelligent beings attempting to communicate with users via visual linguistics, mathematics, morphing colored diamonds of different textures (flesh, gold, liquid metal, colored light). People report beings/entities manipulating what the user can see and view, propelling the user in different directions at disorienting speeds, forcing the user to view both macro and microscopic scale objects including: planetary systems, galaxies, quasars, natural environments, space habitats, technological utopias, neurons, DNA, mitochondria, trilobites, cephalopods, bryozoa and artificial self-replicating machines.
Most users report similar auditory patterns, of a combined high frequency whine, and a slow deep throbbing tone similar to a heart beat. Most DMT users report feeling psychologically uninhibited, clear headed while experiencing peak effects, and able to maintain the ability to think and reason in the above circumstances.
