Often on Ayahuasca I feel extreme empathy for plants and feel like I communicate with them without spoken sounds. Sometimes I wish that it would work that way in real life, it is really wonderful and humbling feeling.
One thing I find rather interesting is that a lot of people who trip on mushrooms mention that they see the world around them much more vivid and alive, especially when being out in nature. I've always wondered if this was something beyond some kind of chemical reaction in our body.
