Welcome Randomiza!
Good to have another intrepid young explorer joining us! As far as breaking through goes... If it had happened you would have known. But sub-breakthrough experiences can be very powerful as well.
I've always thought of myself as a rationalist, but exploring psychedelics for over 20 years has led me to drop the "atheist" label. It's too fixed and specific of a definition. I do believe that all the world's religions are manmade and therefore false, but if you take away that part, there is something great to be gained in recognizing our universal interconnectivity, our common heritage, our shared dreams. We are all one... And yet the manmade religions would have us believe in the "saved" (members) and "damned" (non members). It's all so obviously man made, and yet out of fear, some folks feel compelled to abide. One of the great gifts that psychedelics have to offer is the distinction between religion and spirituality, which is a unique personal experience.
Anyway... Glad to have you here!
