Sounds like a nice experience.
I liked the awareness of your hand as a separate entity, pretty interesting. It makes sense if some see the unity between all things on their trip the opposite could happen and the separateness to a further extent than normal within the unity could also be made visible.
thanks for sharing
btw I wrote a note on my first trip, it looked like a 3 years old had written it.
I cannot fathom trying to play guitar while in that state.
