Salvia especially to me proved how absolutely weird and odd can an experience be like. The brief moment of thinking you are dead only to be instantly put in an experience where you forget you were even a human. An experience where you don't think about the future or past but just feel what you feel right now. Salvia is weird also because it doesn't change what you see but what you feel too.
Psychedelics are fascinating. All my experiences though come down to a powerful realization that all that I experience is all that life is. It's very God like feeling.
