On the other hand, there have been certain psychedelic experiences that have really reminded me of how freeing the disidentification of the self and the mind can be. Here you are, a unit of awareness, thrust into a random life that you did not choose, to a destiny you do not control. Armed with that knowledge, it's possible to summon an extraordinary amount of self-belief, and really extinguish a lot of self-doubt, because you know that whatever choice you make - it was the only choice you were ever going to make, so why not just trust yourself, accept whatever the outcome, and continue to experience life, and feel your choices, relishing in the magic sensation of enacting your will in the world through the instruments of your mind and your body. In this instance - in fact, free will is not really an illusion - free will is an expression of causality, of the flow of the universe, of events set in motion since the beginning of eternity, as far as such a concept makes sense - and as such, that is what you are. It's also not all you are, it's just all that you can experience, incarnate as you are in your biological body, in this temporary life and all it's wonder.
But, those insights are hard to hold onto, and it's easy to forget, to start identifying with the chatter of the mind again, intrusions into consciousness that you did not will and do not control and yet, somehow start to believe, feel some responsibility for, and again, identify with, even though you are not your thoughts, and you are not your emotions. I believe that psychedelic trips could go the other way, and this disidentification, exposure of the illusory nature of the self, could manifest as a feeling of being trapped in a life in which you have no agency.
