5-Level Mapping of Psychedelic Experiences:

 Level 1
This level produces a mild 'stoning' effect, with some visual enhancement (i.e. brighter colours etc.). Some short term memory anomalies. Left/right brain communication changes causing music to sound 'wider'. Can be achieved with regular doses of cannabis and MDMA and with low 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 of 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 high doses of cannabis, low to moderate doses of psilocybin mushrooms, moderate doses of mescaline cacti, and normal doses of MDA.

Level 3
Very obvious visuals, everything looking curved and/or warped patterns and kaleidoscopes seen on walls, faces etc. 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 normal doses of LSD, psilocybin mushrooms, and normal to high doses of mescaline cacti.

Level 4
Strong hallucinations, i.e. objects morphing into other objects. Destruction or multiple splitting 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 moderate to high doses of LSD, high doses of psilocybin mushrooms, and very high doses of mescaline cacti.

Level 5
Total loss of visual connection with reality. The senses cease to function in the normal way. Total loss of ego. Merging with space, other objects or the universe. The loss of reality becomes so severe that it defies explanation. The earlier levels are relatively easy to explain in terms of measureable changes in perception and thought patterns. This level is different in that the actual universe within which things are normally perceived, ceases to exist. Can be achieved with very high doses of LSD (1,000+ microgram), extremely high doses of psilocybin mushrooms (10+ dried grams), and normal doses of DMT.
