Time distortion is an effect that makes the passage of time feel difficult to keep track of and wildly distorted. It is usually felt in two different forms: time expansion and time compression. These two forms are described and documented below:

Time expansion

Time expansion can be described as the feeling that time has slowed down. This commonly occurs during intense hallucinogenic experiences and seems to at least partially stem from the fact that during an intense trip, abnormally large amounts of experience are felt in very short periods of time. This can create the illusion that more time has passed than actually has. For example, at the end of certain experiences one may feel that they have subjectively undergone days, weeks, months, years or even infinite periods of time.

Though the effect of time expansion in general can be felt with virtually any hallucinogen, it is often experienced most consistently and profoundly with the tryptamine psychedelics such as psilocin and DMT. Studies have demonstrated that psilocin, the active compound in psychedelic mushrooms, significantly impairs subjects' ability to gauge time intervals longer than 2.5 seconds, impairs their ability to synchronize to inter-beat intervals longer than 2 seconds, and reduces their "preferred" tapping rate. These results are consistent with the drug's role in affecting prefrontal cortex activity, and the role that the prefrontal cortex is known to play in time perception.

Time compression

The second form, time compression, is more common within stimulating substances than hallucinogens. It can be described as the experience of time speeding up and passing much quicker than it usually would when sober.
