Effects vary widely by individual, dose, and context.
The physical effects of psilocin can be broken down into two components all of which progressively intensify proportional to dosage.
The head space of psilocin is described by many as extremely relaxing, profound and stoning in its style when compared to other commonly used psychedelics such as LSD or 2C-B which tend to be energetic and stimulating. It contains a large number of psychedelic typical and unique cognitive effects.
Psilocin presents a full and complete array of possible visual enhancements.
The visual geometry that is present throughout this trip can be described as more similar in appearance to that of 4-AcO-DMT, ayahuasca and 2C-E than LSD. It can be comprehensively described as structured in its organization, organic in geometric style, intricate in complexity, large in size, fast and smooth in motion, colourful in scheme, glossy in colour, blurred in its edges and rounded in its corners. They have a very 'natural' feel to them and at higher dosages are significantly more likely to result in states of Level 7B visual geometry over Level 7A.
Psilocin and its various other forms produce a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of many other commonly used psychedelics.
The auditory effects of psilocin are common in their occurrence and exhibit a full range of effects.
These combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.

Adverse psychological reactions including anxiety, paranoia, delusions, and psychosis are possible, particularly among individuals predisposed to mental disorders. Psilocybin can precipitate or exacerbate latent mental illness, and those with a family history of schizophrenia or early onset mental illness are at elevated risk. Lasting psychological problems are rare when experiences are properly managed.
Seizures are a rare effect, primarily occurring in individuals predisposed to them, particularly when in physically taxing conditions such as dehydration, malnourishment, overheating, or fatigue.
