The first time I smoked salvia I had a total breakthrough. After all my years of tripping it was well I've never been HERE before! Immediately I began hearing a voice talking to me. It was playful and teasing and seemed more intelligent than myself. Reflecting back on it I have the feeling that it may have been my own thoughts but what makes me wonder is that words originated somewhere outside of my own usual process of forming thoughts etc.I can't say for sure but its 50-50 whether it was an entity or my mind playing tricks. Also encountered a huge eye on shrooms which followed my every move for 2 hours. That was scary and I could actually hear it thinking by looking into the eyeball.
