Sometimes when I meditate, it seems like I am able to let go of my mind. My thoughts will start to go crazy and weird ideas and delusions will start to pour forth like a waterfall. Sometimes I will see thousands of pictures fly by me, memories... "life flashing before my eyes" kinda thing. It definitely seems like this attachment or identification with the cognitive faculties is a very deep attachment in me. I am quite inconsistent at being able to get there, but when I do, it is very relaxing. I often notice a similar going crazy of the mind as I am falling asleep sometimes. Do you have any tips or tricks to help do this more consistently?
