i love to listen to psychedelic rock when im trippin, i just put on some pink floyd, hendrix, Cream etc..and close my eyes while listening to the stellar guitar playin and get lost in the closed eye visuals until im in a trance. any music you dig like techno or rap even will get you there. nothing for me compares to classic rock though. im a huge hip hop junkie but i get such a jonesing for classic rock when im under the influence.
going for walks in forests too is real fun or even a big park near by with lots of trees, plant life looks so interesting when your on psychedelics
even having a shower while your tripping is ab fun thing to do
