As you are doing whatever activation technique you want to use, pay attention to any extraneous thoughts that spontaneously show up. Pete says he actually speaks them out loud to see what they are connected with and teases out a fuller picture by doing this. It’s not as if he’s purposefully image streaming, he’s just paying attention to what pops up and then goes with the flow. The stream of consciousness that occurs can often be very profound and insightful.
All the best!
