There are two key components to a psychedelic trip that you will hear anyone who’s ever taken psychedelics talk about: set and setting. Set is your mindset going into the trip, whereas setting is the environment in which you’re taking the trip — including the people that you’re with.
Being in a safe, familiar place is so important. Familiarity with your environment can provide reassurance when other things appear…very strange. Since LSD alters your sense of time, space, and coordination — your environment is even more crucial for a safe trip.
