I have profound dreams with or without the effects of Cannabis. Some of which are eerily similar to yours, as with the motorcycle chase through your "Mexico". Some of my dreams are profoundly psychic, as with the dreams concerning the demise of my band and nearly being shot by a gang. Some are insightful, like my dreams where I scale down jagged, rocky ledges in order to score free beer. (I was an alcoholic then). I dunno, man. My dreams come in waves and bounds. Sometimes I go weeks without having them regardless of my consumption habits. Though, I do miss being able to use binaural beats to induce lucid dream states. That shit is fun. Thanks for sharing.
