I don’t really ever do it on purpose, but listening to classical music like Shostakovich’s symphonies or something along those lines can put me in a bit of trance. I certainly don’t mind it, but I don’t seem to ever seek it out. It is nice and relaxing, though, even though Shostakovich’s music tends to be tense, atonal, creepy, and wild. Also, believe it or not, working on Photoshop can do this to me. I’ll completely forget about everything and all distractions will be gone as I spend a long time editing a photo on Photoshop. Even reading about certain things on Wikipedia, such as languages, can do this.
