One of my most profound but also subtle experiences occurred during a month of experimenting with L.S.A. Of course it wasn't direct visual contact nothing like a million machine elves bouncing orbs to each other this was more subtle.
I dosed nearly every day over the month period and around week two instead of my normal day to day internal dialogue I started to notice another voice which was not mine but feminine in nature. It felt like a line of communication had been opened and I was been informed of habits that need to be altered in regards to my health.This nurturing internal dialogue went on for another two weeks until I ceased using it but that month was a catalyst that permanently altered my perception for the better. One day many years later I could have swore I heard that same voice whispering through the trees when I had a day with sally.
real or not imagined or otherwise it changed my life for the better it wasn't some grand visual extravaganza but it was the most deepest interaction with an energy that wasn't myself I have ever felt.
